Thank you for being so CLEAR with your issue!
Anyway, do you fully understand how the NOISE EVENT works? I don’t (I mean, I do, but I don’t know what all the nodes mean, specifically; I’d have to test them), and I always create my own events from scratch, because if you try to get creative or don’t fully understand how these functions work, they’ll break.
The first suggestion:
Is the CPU/ENEMY detecting the noise? In your THIRD SLIDE, attach to the FAIL condition in the BRANCH a PRINT STRING node. If it fires with the input string text, you have your issue. If not, let me/us know.
