So... I was trying to play Aveyond 1, but instead of clicking the icon on my desktop like I usually do I went through my program files to do it (don't ask me why I can't explain myself), and when I opened it there was just one save file near the beginning of the game??? Also, it was Build B??? So I opened it from the desktop and it was Build C again and it had all my save files. So I apparently have two builds?? Somehow???? I don't know what's happening ahaha
