Unreal Engine Issues and Bug Tracker (UE-35456)

Description

I created a cylinder with a subtractive cylinder inside of it. I also used a box BSP with a subtractive box inside of it and got the crash to repro.

I tried with a sphere BSP twice and didn't get a crash.

I attempted all three on 4.12.5 and it didn't occur.

Crashreporter: [Link Removed]

Steps to Reproduce

Repro;

Create a third person blueprints project.
Add a cylinder BSP into the level.
Copy that cylinder and make the copy a subtractive brush.
Select both cylinder brushes and convert them into a single static mesh.
Create a new actor blueprint.
Add the newly created static mesh into the actor blueprint editor viewport.
In the blueprint editor add a box collision to the static mesh.
Right click on the box collision name.

Result:
Editor crashes

Frequency:
100%
