I've been trying to fix that for like three months now. If you save to disk it'll always work but the save purge on an update is something that can't be avoided
Also I saw your dev log, its not a big deal that the game resets, its really not too time consuming to get back to where you were, the only real difficulty is the fight scenes, but i takes me about 10 minutes to speed run my way back, i made the original post because i was feeling funny ๐
