MR auto deletes unused text, so if you create new dialogue but never call upon it in a field script the dialogue will just be erased.
Nah, that's definitely not the issue, for a couple of reasons:
1. I only touched this field manually.
2. I never use that auto function, doesn't sound useful to me (plus too risky).
3. I made changes not to do with dialogue also.
4. Obviously I did call upon it.
I just copied a fresh ISO and inserted that same script, and now the game just displays the game's default script without any changes at all, though the script IS inserted and viewable in Makou (again at LBA 1227, but its not linking to it). The script isn't even that much bigger than original either. So just seems a litttle strange MassIsoUpdate can handle this properly and Makou can't (since Makou can do everything else
)..
