Custom Map/Event reloads ROM after turn 1

[polarisx]

I've been trying to get a custom map/event to work in Fire Emblem 7, but after turn 1 (Meaning both allies and enemies have all finished their first actions) The game reloads and starts up the opening cut scene, with the "Nintendo 2003" text and such. Resuming the chapter automatically brings me back to the starting sequence as well.

I can load the map with the same events as the prologue, just with the map different, and it works fine. However, if I load the custom event on to the map, it only works for a single turn.

Here's the event I wrote. Nothing too complicated, just made for a really simple test event to make sure I know what I'm doing before I start anything long-term:

Probably unrelated to your problem, but in those events

END_Main should be ENDA.

Tried that, it didn't work. Same exact issue.
