Procedural Mesh crashes Editor when Build Geometry

[Flakky (Alexander Blintsov)]

I have a Blueprint with Procedural Mesh Component in it, and if I just call Build Geometry (Toolbar > Build > Build Geometry) everything will be fine.

But as soon as I add some polygons to my Procedural Mesh Component and try to rebuild Geometry (Or rebuild all), UE4 crashes…

It stuck on Cleaning Up and then crash report…

This has been fixed in GitHub for release at some point in 4.8: Crash on build in editor with UProceduralMeshComponent 4.8p2 - World Creation - Unreal Engine Forums
