Sorry I'll take a look, haven't really gotten to the Beast Quest yet, since someone else said there might be something wrong with the Worm Quest I treid playing through that fist, but I'll take a look at this next. If possible can you message me the save file so I can check it, otherwise I only have the map files and that makes it a bit harder to find.
Edit: I’m hoping you made a backup of your save folder somewhere, but did you do a manual save before that? Otherwise I don’t see anything in the related maps yet, so it might have happened somewhere before you met the chains. This might be something really well hidden since after the last trap I went through everything again to make sure I didn’t miss anything. I think it might have happened in the map you were teleported to before the patch, I can’t seem to find it so if you could give a better description that should help.
Also note that he sets localstorage items so you can’t just start a new game, if you want to you’d want to remove the save folder first then clear the localstorage. I might add something to clear it in the code in the next patch, otherwise if you want to do it yourself you could use cheat menu and open the console with F8 and just type in “localstorage.clear()”.
If that’s too much trouble you can just delete the entire game, extract it again, patch it and play.
