When I work on another blueprint and come back sometimes one that was working has stopped taking input

I have a safe blueprint and a door blueprint in a level. I enable input on begin play in each of them. I know with the wiring set up, I’ve seen the safe BP work, but after returning to it it had stopped. While watching the BP I noticed that the R key event isn’t firing anymore despite the collision box telling it I’m in range, and the fact that input should have been enabled at Begin Play.
