Broken Project

[Ampharel]

I’ve been running into a rather frustrating issue.
Since a few days back, one of my projects randomly got itself corrupted. This may be due to the latest patch, or something completely different, I’m not sure.

The issue is the following:
After opening the map, the output log shows a few errors, and a ton of warnings.
The errors are the following (full log):
LogOnline: Error: EOS: UEOSSettings::GetSelectedArtifactSettings() ArtifactName=[Fortnite] no settings found.
LogOnline: Error: EOS: FOnlineSubsystemEOS::PlatformCreate() GetSelectedArtifactSettings failed
LogHotfixManager: Error: Only 77 of 79 assets were successfully patched from ‘AssetHotfix’ section in the Game .ini file. The patched assets will be forced to remain loaded. Any assets that failed to patch may be left in an invalid state!
LogShaders: Error: Missing shader resource for hash ‘5C93CFF627CDC4806D99EE9CA84A303F98BB4FF2’ for shader platform ‘PCD3D_SM5’ in the shader library
LogHotfixManager: Error: Only 77 of 79 assets were successfully patched from ‘AssetHotfix’ section in the Game .ini file. The patched assets will be forced to remain loaded. Any assets that failed to patch may be left in an invalid state!
LogHttp: Warning: 000005FCD9E54600: request failed, libcurl error: 6 (Couldn’t resolve host name)

Now, I can work on the project just fine, but I cant launch it into a session. When I try, Fortnite will start, and the session will be connected, but instead of spawning me into my island, it puts me in an empty scene, where I just fall for a bit until dying. In the top left it shows Edit mode Error, and the ingame log is completely empty

The curious part is, this project specifically is just a templated island, with no custom assets added to it. There’s 1 verse script in the project, but this is not even added to the scene.
I’ve tried completely deleting the data from this project, and redownloading it from the repo but neither seems to resolve it. For this project specifically, I can just make it again from a template, then move over the script, but I’ve this exact problem on a far larger scene, where completely remaking it simply isn’t realistic.
The logs show it cant seem to find the settings, but the world settings device is present in the scene. It seems to have an issue upgrading some assets, but again, this is just an empty templated world, so I can’t imagine what that could be.

Above this screenshot is only the background folder and a light.

Does anyone have an idea of how I can even begin to approach this issue and find the root cause?

[Ampharel]

Ah and something I should probably add
Making a new level in the same project will have the same issue.

@Ampharel Thank you for your report! We would like to look into this further, would you be able to submit a bug report using the form available here? Fortnite Creative

i have this error too-
LogHotfixManager: Error: Only 77 of 79 assets were successfully patched from ‘AssetHotfix’ section in the Game .ini file. The patched assets will be forced to remain loaded. Any assets that failed to patch may be left in an invalid state!

[Ampharel]

I’ve created the report, after some further investigation it seems like it might be the template itself being broken after the last update. While I’m getting warnings aswel on different templates, the error does not directly appear

[Ampharel]

I’ve actually run into the same issues now with another template. And it even occurs in a blank scene.

I’ve fully reinstalled UEFN, that didn’t resolve it.
I’ve also deleted all assets in the level, that as well has no effect. It seems like UEFN just became completely unusable on this system.

I would update the bug report, but I don’t seem to have a way to get to it

[Ampharel]

@Stevie-Moon Some more information
I’ve tried on multiple different systems, and had multiple people try.
All of the templates are broken, since the last patch UEFN cannot start new projects anymore. This is a huge problem for us, is there any indication of when this would be resolved?

[HalcyonKnight96]

@Ampharel catching up here… as much additional information as possible would be very helpful.

• What templates specifically are broken?
• Can you try replacing the IslandSettings device?
• I see the logs you posted originally point to SM5? Are you using a non-default shader preview platform?
• If yes, can you switch it back to SM6 and retry?

Thanks

Hi, I get a very similar error with:
Error: Only 77 of 79 assets were successfully patched from ‘AssetHotfix’ section in the Game .ini file
My logs: https://pastebin.com/nEiWPeS7

And I get a bunch of:
LogContentStreaming: Warning: [T_Smooth_Tile_Chromatic] Texture stream in request failed due to IO error (Mip 1-3).

Repeating all the time

It happens often from the premade lights in the premade islands

I can however build and test, and this started with 25.10 update too

[Ampharel]

All templates are broken (I think), I’ve not tried all of them, but any I have tried breaks.

I’ve tried replacing the IslandSettings device by deleting the original and placing a new one, this doesn’t have any effect.

With regards to the shader preview. I didn’t even know how to change this so I certainly didn’t do it on purpose, but you may be onto something here:

Sadly I cannot switch it back to SM6 since it’s greyed out.

One thing to note. I’ve been able to get a project working by using a working project from before the last update. Then using a “Save as” on the existing level, and using that as the basis to make my new game from. I’ve checked to be sure, and that one is on SM5 as well, with SM6 being greyed out.

[HalcyonKnight96]

@Ampharel after investigating this more it’s possible your GPU doesn’t support SM6/DX12, what GPU are you using? Also, I think I’ve pinned down your issue to some cook failures on our end, we’re investigating this now.

[Ampharel]

RTX 2060

Also, I can run existing projects just fine. It’s just making new projects using templates that breaks. Beyond that this wasn’t an issue before last update.
While I wont discount your suggestion out of hand, I find it highly unlikely.
I’ll see if I have any driver updates that might fix it somehow.

Beyond that I’m seeing the same problem on my old workstation, though that one does indeed have an older GPU and I’d expect that one to have issues. It’s using a 960 GTX from the top of my head

did you ever find a solution?

[BubbleBunz]

I have a similar issue, except, ALL FORTNITE ASSETS and DEVICES, were removed from my content browser, in the Viewport, and the outliner of ALL my projects as well. This randomly occured after “Verifying files” last night and opening the project.
UEFN and all of my projects devices are gone, and it is unusable.

Class Selector For Example

Hi @BubbleBunz we are looking into this last issue, but it sounds like it maybe a different issue than the original post.

[BubbleBunz]

@A1go I appreciate you looking into these errors! I also have a major bug repeating weekly / bi-weekly since Deemeber 2023. The earliest screenshot of this repeatable bug I could find reoccurring weekly was back in December, and still occuring weekly to date.

The World contains invalid actor files click repair.

All Fortnite Creative Devices, prefabs, and other files and folders disappear / are deleted from content browser and from viewport and outliner

Repair / Source control repairing task % completes but says Failure. (Sometimes I am luck and few days to a week later, the FNC content populates in the engine again.
I need to add, that this happens in every single project, and not just one. So when the repair issue populates, it affects not just one, but all of my projects I open. Even new blank projects.

Thank you for your response!

Hopefully this is not too much trouble to ask. This is a critical bug that has slowed me down the last couple months.

[SGSensei]

This is still a major issue for some people. It seems the issue is project specific. Although, whenever I open the project on a brand new computer, I can typically work in it perfectly fine until I close and reopen again. Then all the actors are broken. Not only that, but if I switch to a known working project after, it also breaks (doesnt seem to stay broken though if you close UEFN and reopen directly). I have the same issues as described above. Actors broken, 95% of devices missing in content browser, devices already placed in the game world are invisible (can still be found in outliner, highlighted, and details accessed etc).

I’m getting a similar error on multiple projects that were previously fine.
