I’m rotate actor (not Component directly (!) ). Actor have StaticMeshComponent. StaticmMeshComponent is a RootComponent. I’m extract world rotation from StaticMeshComponent for function ComponentSweepMulti(). I’m rotate actor in Editor and watch bug in game. If rotation set to 0 then ComponentSweepMulti() correctly working.
My UE version is 4.7.6 / My English bad
