Crash copying a Static Meshes primitive collision member and pasting it on another element. The pasted element seems to need at least 2 members for the crash to occur.
Editor Crash when adding collisions to a static mesh by copy/paste of array elements. Reproducible: 100%
Results: The editor will crash
The above repro works 100% in 4.15. I was able to reproduce it in newer builds with similar steps. Sometimes adding additional collisions is needed and copy/pasting back and forth several times before the crash occurs.
