Hello.  
I am using UE 4.21 for my project.  
During production I noticed that at a certain amount of brushes, some of them are cutted off: some polygons just disappearing. **Build All** button didn’t help.  
I tried to convert brushes to **Static Meshes**. When I press a button and enter a proper name, my brush teleport at 0;0;0 and no mesh was created.  
Please help with those 2 issues.

I figured out how to create static mesh. I move brush to **Persistent level,** then convert it ti static mesh, then return back ti its level. Well…it works. But questions are still up
