behavior tree task:controlled pawn is not valid?


is this a bug?when running the game ,it seems work properly.but if I stop it will prompt me says that controlled pawn is not valid?the pawn never gets destroyed.i tried as picture above.

thanks !

additional background:I know this is an abort event .the task is a looping chasing an enemy.the task doesn’t have a finish node.I use abort event to stop movement.
