I’m having the same problem in UE 5.1 and the only solution for me was the following procedure. (I know it’s a bit hackie but …) You can add an Event-Track to the ActorSequence and then Trigger an Event before the Sequence finishes … in the implementation of this Event you can then stop the Sequence before it reaches its end. Please give me your feedback if this works for you as well guys … Thanks and happy coding
