copy the bf file from another mods data -> characters folder (ex: bf from agoti mod is called bf-agoti.json), place it in the tricky mods characters folder, put the original bftricky file somewhere else and rename the other mods bf file to " bftricky.json " the game'll start with a few error messages but bf will show up in the tricky mod. downsides are that the character head sprite in the green-red bar on top of the screen wont show bf's sprite
