In the flesh area there is a spot that is weird and buggy. in a cross section that has a bit more space open (3 tiles each) on the NE and SE side, when you go to the east you get the flesh pet cutscene. But I thought it softlocked because it tried to go down while an enemy was in the way. Thankfully the enemy eventually moved and let the cutscene play. But after I moved one step forward the cutscene marker was there again and now played a different scene where it went another way. It was very confusing. But it did not actually cause any problems.
At the flesh boss the battle starts when I step on the stairs. I did not realize this for a bit because I can freely walk around the arena and even try to talk to the boss with no result. It was when I went to leave that the scene then began to play. I think one of your wall tiles became a floor tile.
On a similar note I can walk over the hole that goes down in the new area. It looks pretty silly. but yes if I touch the hole with the vine over it then I go down.
Instead the game breaking glitch I had is that I used the crystal skip to regain my lost progress after the update and ended up recapturing the slime while backtracking despite having it equipped. To my surprise, you have a message specifically for when I try to add the slime to my inventory while I have the slime equipped, so you can detect that, but nothing is done to fix this??? Stranger than that, is that when I used the pet reset with two pets available, I go to try and take one and both of them will say I already have a pet. But I check and the one in my inventory is gone. So the pet fix actually disables pet use entirely, which is worse than being stuck with two slimes. I tried later after I got the 3rd pet and still not letting me use any pets at all.
Oh and is the slimewall meant to be a random encounter? I didn't think this game used random encounters but I keep being attacked by the slime wall any time I walk through a slime area. I wanted to provide some screenshots which is easier done over Discord. But you keep closing those Discord invites!
