Collab Viewer broken in 5.6

Opening the Collab Viewer start file in 5.6 now gives a broken and unusable project. Something happened between 5.5 and 5.6 that breaks the camera/player controller. If you load up that file in 5.6 and try to navigate the scene in Play Mode you will see that the character tries to turn but then is pushed back to be forward-facing. Is there any fix for this? Thank you.

I found a workaround. It seems that removing this connection on the BP_Base_Pawn at least seems like it works as intended again, but not sure what this is supposed to be doing.
