[Error] MoveFromPin was nullptr

I getting this error when trying to compile my player BP:

[2016.02.26-11.27.20:482][144]BlueprintLog: New page: Compile rooMazePlayer
Exception thrown at 0x00007FF8FA7B8DFE (UE4Editor-Engine.dll) in UE4Editor.exe: 0xC0000005: Access violation reading location 0x0000000000000138.
Unhandled exception thrown: read access violation.
MoveFromPin was nullptr.

I getting it after copying this:

from other BP

I found problem. Validated get can’t be used inside of function. I just use “Is valid” node but fix it please.

Hello,

Since you have been able to reproduce this issue, could you provide steps to reproduce it in a clean project? I have attempted to use a validated get inside of a function, but I am not seeing the error that you are describing.
