TRICKYNICKY'S PROFILE

Has anyone ever known Battle Processing conditions to fail?
This event has always - and by always, I mean every time for the last 15 years - run perfectly until today. You enter a battle which ends by you getting knocked out instantly which progresses the game to the next part. And yet playing through today, when I get knocked out, it's game over instantly instead of processing the "If Defeated" condition in the event. Nothing on this map has been changed since last time I played through. In fact, I played through multiple times recently before I uploaded the game to itch.
I do not know what is causing the event processing to fail.
What is different today that is causing it to glitch? This event has never done this in the 15 years since I first created the event.
I need help!
