When using a blueprint with a destructible component, you can call the SetCollisionResponseToChannel node of that component in the construction script. As a result the engine will crash when attempting to compile.
Worked in Binary 4.13.2 CL 3172292
Broken in Binary 4.14 CL 3195953
RESULT
The engine crashes
EXPECTED
No Crash
REGRESSION?
Yes
