tstrongvfx · March 9, 2024, 4:34pm

huh not working for me. when i rebuild project they come back in corrupted

tstrongvfx · March 9, 2024, 5:04pm

i just dont get how this happens

tstrongvfx · March 9, 2024, 5:15pm

what do you mean by all “all files in fortniteprojects”

KryyssX · March 9, 2024, 5:33pm

v29.00 is an absolute mess. I have to wonder how thorough they were testing it internally. We’re seeing everything from file corruption and editables being wiped every time you rebuild verse to validation errors on existing fortnite assets and projects failing to push.

The wise thing now is for everyone to just stop using UEFN before they end up losing work and wait on Epic to get their act together.

Hi all, apologies for the issues you’re running into with this. I am currently looking into this and having trouble reproducing this internally. If you’re running into this, could you help provide some additional information here:

If you just create a brand-new project from the Blank template, add a new Verse script with the default hello_world_device, do you also get the same issue?
Just to double-check, do you see the exact same errors in the LSP when you look at your Verse code in VS Code?

Thanks. Any additional information you could provide here would be helpful, such as if you notice this only happens with specific projects, or literally every single project you create/open.

I have ran into the same kind of errors and even in a brand new map with a hello world script, I get errors

sonictke · March 9, 2024, 11:53pm

@eks_2007 and @bigtail, could you please attach your full editor logs to this thread?

Fub · March 10, 2024, 3:06am

Getting this issue as well across all projects.

If I make a new project, the issue appears the moment I create a new “hello world” template file.

sonictke · March 10, 2024, 3:29am

Hi @Fub, could you attach your full editor log to this thread? Your issue appears to manifest slightly differently from the original issue described by @bigtail. Are you making a new project based on the blank template, or some other template?

Additionally, if you attempt the workaround described above (where you clear out the intermediate files in %localappdata%\UnrealEditorFortnite\Saved\VerseProject\FortniteGame, does that somehow resolve the issue?

Fub · March 10, 2024, 4:11am

If I open a fresh instance of the editor, make a new project based on the Blank template, create a hello_world_device, then I get no errors.

However, if I load an older project where the issue persists, it then affects all the other projects if I subsequently open them. I’ve attached the logs

I tried to delete the files in the directory you mentioned, including the directory specific to the troubled project, and that didn’t help.

Fub · March 10, 2024, 4:44am

Deleting that folder did it.

I also had to fix my own verse compilation error in the trouble project,(preventing the code from rebuilding?). All is working again!

Nooberling · March 11, 2024, 6:49pm

Same issue in one project, I now have several projects I am scared to open.

My log file is attached, hopefully that will help you.

Thanks for the additional info everyone.

For those of you who experienced this, could you clarify: did your projects have Verse code that triggered warnings/errors when you first opened your project and then clicked [Rebuild]/[Continue]?
