4.12 Garbage collector crash while using sequencer

When i edit my level sequence and save it, UE4 closes always with the same error:

The thing is… i don’t have a D: drive, can it be the reason of the error? (UE4 looks for GarbageCollection.cpp in D: But doesn’t find it?)

EDIT: Removing “actor to track” from CineCameraActor solved the problem! I leave the thread for bug hunting ;D
