I crashed during the the 6th level(The ice one) and I reverted to an autosave back in the pocket dimension. Afterwards, I tried to encrust a polearm with the ultimate radianian crust and then saved and quit to make a new save with it in case of another crash, and I didn't want to loose the crust as it didn't get unstable. After I loaded the game, it crashed when I attempted to leave, and happened anytime I loaded. I applied the hotfix test3+test7 to my instal, which prevented the crash, but now instead of leaving the dimension, I end up just resetting the cooldown, which still counts down in the dimension. I can enter the wizardlands, and attempted it to see if i could escape. Instead I got another crash, and now when I load, the dimension is all black so I can't see anything other than tooltips above my stashes, and I can blindly stumble to the portal and leave to a wizardland. The display works fine in the wizard land, but when I return, the dimension is in the same state.
Loading any save that was saved inside your pocket dimension or the wizardlands will crash the game as you exit the pocket dimension.
I think this extends to mysterious portals too? Or at least it was that way for me over the weekend. I ended up avoiding all mysterious portals, not using my pocket dimension, and thus not visiting any Wizardlands for the latter half of my weekend because I just wanted to get further in the dungeon without constantly crashing. Hopefully the fixes that are in testing can clear this stuff up. I would love some uninterrupted time in the dungeon.
