Hello,
I’m working on my level in UE 5.2 and created some level instances. Nothing special, just a simple building with walls, windows etc. I create Level Instance by selecting all meshes and then Level → Create Level Instance. Everything works fine until I exit the program. After restarting the program, the model is missing e.g. a door. The funny thing about all this is that each time you run the program, other parts are missing. I encountered this bug in 5.0.3 but in 5.2 it still occurs. Has anyone had a similar problem and can share their thoughts?
In the attachment I add a photo that shows the same level instance. In one part of the roof is missing, in the other everything is ok. When I try to reload the same level instance, everything displays fine until the next program launch
