I wouldn't know how to explain this without the attached screenshots. - In the first one, I re-logged in at Vesper bank. I could turn around but not move, until after a minute all was back to normal. - In the second one I was just out of Delucia-to-Trinsic passage. The black area beheaved like a wall and was all around in a radius of about 40 tiles I guess. I went back into the passage, then out. Only that I didn't appear out, but instead I appeared in the cave again, like if I just entered it. Once out for the third time, all was normal.
