Sorry for the double post. The issue was surprisingly simple to resolve: I just had to split up the exports instead of do them all at once. Here's the MTL for the updated version of FantasM, 0.75, everyone.
Good news: this updated version of Translator++ seems to have resolved one of the issues I was having previously, so now all of the boss refight lanterns and reflection pools should have their options fully translated!
Unfortunately, the issue of translated text not appearing in-game persists with the teleport menu. I managed to narrow down which lines in Translator++ correspond to the text that is supposed to show in that menu via one of the few that is translated correctly (bringing up the search, changing the target to "context", and typing in "script/13" will point to the name of each map's teleport). I'm not sure why it's still not appearing even though the reflections now do, nor why only "Heavenly Palace Playground" is the only one that shows up correctly, and I'm still not sure how to go about fixing it. Contrary to what I previously understood, the Raw tab at the bottom of the screen in Translator++ doesn't allow me to actually edit the javascript. To do that I apparently have to use something called the "

" menu, which doesn't seem to be where the screenshot on that page shows - but that page seems focused on RPG Maker MV projects, so maybe it just isn't available for XP projects like FantasM? I'm at a loss.
Regardless, I hope it works well for everyone! Remember to have the language set to Japanese in the Settings so it pulls the text from the correct locations.
