Typically we don’t save or modfiy files inside the engine folder. Make a copy (or use ‘save as’) to your project folder (content) and give another try.

I’ve moved this over to the World Creation subforum. It’s a better location to ask this type of question. :slight_smile:

I got the same thing a couple of times. Looks like a bug. Here is a video.

Looks like this is a bug related to Auto Save in the engine.
In order to prevent this from happening - go to Edit => Editor Preferences => search at the top bar “Auto Save” and turn off the checkbox.

It should fix it.

Having the exact same issues as well. Is there any other option then the auto-save idea?

I’m getting this as well.

Same, driving me nuts. And when trying to unload the level (opening another level), the editor crashes.

Same problem with UE 5.0.3

Will give this a try, thanks!

I managed to fix it like this:

  • I had a material on an actor, and the material was under the “Engine” folder.
  • I replaced the material on the actor with a new material, which was not under the “Engine” folder.

Probably meshes and other stuff under “Engine” cause the same behavior. I think we’re dealing with a genuine bug, but at least there’s a workaround (hopefully it will work for you too).

For me, it was just numbered autosaves. I simply deselect them (don’t save the autosaves) and move on.
