Anim montage won't play

Here is the BP:

The montage I chose (Death1) worked for another actor. Here the montage just won’t play, even though the print string “Completed” fires, which means it was completed.

I am in experienced with animation, so maybe it is significant: I didn’t prepare any animation BP or state machine for this actor, from what I understand playing montage doesn’t require it. Correct me if i’m wrong.
