Loving the hack so far, unfortunately I'm also facing the problem of the game just straight up freezing in Mystifying Forest during the graduation, after falling into the pit. I used the randomizing options and got Deoxys and Weavile as starters, in case that matters, I also did not have any problems in Quicksand Cave before. Attempted to load the save into Vanilla and tried it again, this time game did not crash but softlocked instead.
Would it be a potential workaround to switch to Vanilla and use cheat codes to switch starters to "intended" Pokemon for the time being? Or is there any other workaround?
And if not, is there any ETA for 3.1. seeing as you apparently fixed it on your side?
Thank you for the work so far in any case.
