For some reason, this plugin doesn't seem to be compatible with Moghunter's BattleHud or Yanfly's Party Manager.
It spits out this error by the way:
It's odd though, because it was working fine earlier, but eh, maybe I was just lucky.
EDIT: I'll keep investigating further, but it seems to work without any save data located in the save folder, but at the cost of not allowing save data to work.
It reports "Error: Object too deep {stack: (...), message: "Object too deep"}" When attempting to manually save the game.
EDIT 2: That was fast wasn't it? Figured out it was this combined with another plugin I was having problems with in the past. Specificly the one Found
here.
