Can we just stop move the stuff in the AppData folder to the folder the game is in? I just want my porn games to all be on one drive, not have it half on one drive, half on another.

If you want to manually change this:  

• Make a folder within the main game folder called "savedstuff"
• If you want to retain your existing config/saves, copy (or move) the "saves" and "savedcharacters" folders, as well as all the loose files (progress_data, Settings.ini, and any others) to the savedstuff folder.  (If you don't do this, the game will create default versions like a new install.)
• Open up src/core/variables.gd in your favorite text editor.   Find the line "var userfolder = 'user://'" and change it to "var userfolder = 'res://savedstuff/'" .
