Do you remember the last things you were working on with it.

I think I just added some movement devices like Bouncers, D Day Launchers and I flattened some landscape… nothing else

And I tried everything to fix it, reinstalling uefn, duplicating the map, reinstalling epic launcger, chaning some grapic settings etc. …
