It will be really good if you can manage the archives what replaces the patcher, anyway i did a backup of my data folder for futures versions o/.
By the way, i forgot that in some points of the early games, i had to play the mod in a vanilla version of the Steam game, without any mod except the yours, for example, in the motorbike minigame, and when i "get" Aeris from a Phoenix Dawn, in this one, i had to able Aeris on my Phs and party via Black Chocobo, i think it's a model problem, there istn any pop up from the error, just the screen turn black or freeze, then i have to stop the application, there is a windows with a "An unknow error has occurred" message, but as i said, i think it's about models problems.
