ADK Crash on Save

Running into this strange crash almost every time I save. Not too sure what could be causing this. Any help would be greatly appreciated. Thanks for your time.

Updated my Graphics Driver just in case, still same issue.

This looks unfamiliar to me. What files have you modified recently?

The only thing I can really think of is that I copied some Foliage assets to my Content Folder that are used within the Shared>Redwoods>Foliage Folder (The Sword_Fern_01).

I did this because it wasn’t showing up in game. Now the Foliage shows in game but the texture is missing which isn’t a big deal, I just need to be able to make it save!

Maybe I should delete that foliage layer completely and see if that changes anything? (That foliage was already in the map, then because it didn’t show in game I replace the mesh and Foliage Settings with the ones within my Content Folder. Maybe that’s where I went wrong?

Thanks so much for your help.

Yea, try that out and let’s see if that fixes the crash. I know there’s also been some issues with the newest Nvidia graphics driver that’s causing crashes. Not sure if it’s related though.

I took out the Ferns and it was able to save. So then I decided to continue on with more ground clutter. Then save and it crashed again with the same error.

Is there some possibility that I’m putting too much ground clutter down or something odd? I don’t know too much about what UE4 can handle or not.

Maybe too much ground clutter/assets on one level? Is that possible?

Thanks for all the help.

Not too sure if I’ve solved this issue yet. . . However I think it may be related to having too much foliage on 1 level. It seems if I add more grass to that level it will crash on saving again. Although trees and rocks can still be added to that level without save issues I believe.

I’ve this problem and similar ones when unloading streaming levels - I can re-do what I did but it’s seemingly random.

I think this crash was related to the ridiculous amount of assets in the one level. It was fixed by deleting assets from the ground and putting them on the Clutter Layer instead.
