I create a skeletal mesh.  
I create a multi-convex collision for a wheel.  
I then reset the collision for a sphyl.  
I click a remaining convex entry.  
I hold shift to select another convex and it causes the editor to crash.

Hi Doublezero0 -

So far I have not been able to reproduce the crash that you are experiencing. Can you post the Machine ID from the Crash Reporter that you submitted the crash with and if possible can you share the FBX that is causing this issue for you?

Thank You -

Eric Ketchum
