Pony Fantasy VI Remake

Okay, spent a good part of yesterday and an hour today troubleshooting this to no avail, so I'm breaking down and asking for help.

My moving of Umaro's recruitment to Lola has gone great, the event itself works fine, I can make the flowers in Lola's house not appear when recruiting her, Lola herself stops appearing in the house once she's recruited, and as a bonus, all the new recruitment stuff fits perfectly in the space for the old event for talking to Lola, provided one simplifies the events with the letter and Cyan switching them (a feature I wanted to remove anyway). I also checked all the other times you talk to her and it works fine (playing right from the moment you get the airship to be certain she works fine, and also going back in the WoB). And so far it seems like the game properly notices Umaro/Lola is recruited - she appears aboard the airship, in the party select screen, in shop menus, can be chosen as party leader and looks fine as such, and she works in battle.

The catch is there's an issue with her battle palette. She uses the same Palette 0 that Umaro was using, but is miscolored in battle. I double and triple-checked her palette assignment on recruitment and the battle palette saved for her in usME, all are fine. I tried recoloring her sprite to use Palette 4, using only the first 12 colors (Rydel's patch lets me use 13-16, but just in case). What followed was another miscolored sprite. As another experiment, I took Lola into battle with Edgar, who is also on Palette 0 and uses some of the same colors as Lola; Edgar looks fine. Reimported Umaro's sprite and changed nothing else - looks fine, Reimported Lola and changed nothing else - miscolored in battle.

Soooo yeah. No clue what's going on here.
