4.12 Garbage collector crash while using sequencer

[p4cm4n]

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

Fatal error: [File:D:\Build++UE4+Release-4.12+Compile\Sync\Engine\Source\Runtime\CoreUObject\Private\UObject\GarbageCollection.cpp] [Line: 539]
Invalid object in GC: 0x00007ffb67f2f128, ReferencingObject: CineCameraActor /Game/Maps/Black_Hole.Black_Hole:PersistentLevel.CineCameraActor_0, ReferencingObjectClass: Class /Script/CinematicCamera.CineCameraActor, Property Name: ActorToTrack, Offset: 2064, TokenIndex: 29

Crash in runnable thread TaskGraphThreadNP 0

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
