Game keeps recreating Lake Nur 3 [1.1.5]

[Fungah]

Playing a Paradox Mage recently and got up to the Weirdling Beast. I ended up needing to use Precognition, then decided to start stairdancing. When I went downstairs, the game generated an entirely new Lake Nur 3, as well as displaying the starting dialogue and picture again. When I went back upstairs to keep fighting the Weirdling Beast, it was back in its starting square (I'd managed to lure it to the downstairs) and the game displayed the dialogue that pops up when you enter the zone for the first time again. I end up using Precognition again, try stairdancing again, and end up in a third incarnation of Lake Nur 3. Again, same opening dialogue, new enemies, new map, the works. I go back upstairs, and the Beast is where he was when I went downstairs, and when I go back down it stays on the third version of Lake Nur. At this point the Beast brings out the big guns, kills me, and I decide to let my poor Paradox Mage die and call it a night.

Here's a link to my log from where I enter Yiilkgur until just before my last death: http://pastebin.com/Vp6aw1QU
