I have a bug report. It's already reported, but i narrowed it down very exactly.
Take a savegame (in which i already successfully edited a bit), open in black chocobo, save, loads (in fpse emulator) with no problem.
Equip my crew with ribbons in stead of champion vests, open in black chocobo, save, "file is ruined" when trying to load.
In this file:
https://www.dropbox.com/s/jx75enk0kf5ioxt/BeforeAfter.zipslot1.before_edit.mcd and slot1.after_edit.mcd
in slot 1: champion belts, no problem
in slot 2: ribbons, openening after_edit gives "file is ruined"
PS1: i couldn't find a way to attach files, so i hope the zip/dropbox method is ok
PS2: i used the latest editor, portable windows version: Black_Chocobo-static_1.9.80.1132.exe
