Me and my friend where playing and at some point we kinda just split up
Later i noticed my friend was in the walls, and they said i was in the walls for them, i also didnt see any enemys. truns out at 1 of the rooms where the left side was open for me, the right side was open for them. so the whole second half of the dungeon was de-sinced for us, and i teleported to them and fell in the void, so there just was no dungeon there for me.
later when he got to the boss i teleported to him so he could fight the boss wich worked but i just fell out of bounds again, and when fun y defeated the boss my map unloaded, casing me to fall in the void repeatedly (softlocked)
My friend wasn't softlocked and if i had died before teleporting to him so i could float id also have been fine but didnt think about that
My friend was the host on pc and i was on quest, we also had no mods installed and we had the same seed, everything before then was sinced
(My friend will upload his POV of the bug and a screenshot of the seed in a bit here)
((And the seed was -1656517848))
