When pasting nodes with references to an event tick into a function then compiling the editor will crash.
Regression from 4.12.5 Binary CL-3039270
Edit - TravisL: I was able to repro this crash on CL 3104135 in //UE4/Main
Found on:
//UE4/Main CL-3104392
//UE4/Main CL-3104135
4.13.0 Binary CL-3103819
