Unreal project randomly broken.

Hello everybody,

I’ve got a problem with my project and i’m clueless to what happened. This morning i saved the project and that went all fine and everything was okay.

Now i’ve started up the project again in the evening, and it seems like my project partly crashed.

Several actors are showing strange behaviour and have been manipulated. I used to have a map and now it’s mainly a big empty hole. I had rooms that i made into actors, and these are very different now. Floors are missing, other parts have been moved around. Walls are blocks now and i don’t know what happened. Feels like unreal is bugging out and i can’t get it back.

The problem is that i was using on this project for a school assignment, so it be quite devastating if my project is broken since i’m on a deadline. I hope anybody can give me some advice about what is happening or what to do.

I haven’t gotten any errors and unreal did not crash before this happened.

Picture 1: There used to be a full map here.
Picture 2: This is how some of the rooms used to look like.
Picture 3 & 4: This is how my rooms look like now.

Any help would be greatly appreciated.

In your fourth picture it looks like the static mesh components are still in the Blueprint hierarchy. But they probably have no reference to a static mesh. I think the most likely thing that happened is you saved your Level but not all assets. Something that can trick beginners is the fact that everything in UE is a reference to other assets and other files on disk. If you reimport whatever those missing assets are you should be able to go to those Blueprint mesh components and point them to the right model again.

Thank you kindly for your response!

I have been messing around a little bit with testing other projects i had which still worked and i was a bit stumped.

In the end i fixed the issue. I am not sure how or what happened and how it got fixed, but i coppied the whole folder where my project was in and pasted it on my destkop. After that i opened the newly copied project and it all worked fine!

I am a little confused though, since i litteraly just copy pasted it over and all of a sudden it worked.

Thank you for your response!
