I've managed to locate the old files and implemented a fix for the tutorial soft locking that was preventing new players from hopping into a fresh dungeon.
As a result of years of engine updates, the file structure is also a bit different so the update will change a bit more than just the quick fix, but my tests have everything running fine over here. This may reset options settings for veteran players, but should not reset progress.
Let me know if you have any further issues!
