Yeah, I forgot a important thing to tell you.
In editor, I ejected from a player controller.
First, I moved an actor into the volume of another actor and “Begin Overlapped Event” was triggered.
Second, I moved an actor out of the volume of same another actor, “End Overlapped event” was not triggered.
The Point is that I moved an actor by cursor directly.
Everything seems working fine except for the case I moved an actor directly by cursor in editor ejecting from a controller.
Plus, there were no errors on blueprint debugger.
