died in ambush; Ukruk spawned twice

[Flare]

At level 35, my yeek paradox mage just finished Dreadfell. (I did nearly everything in the west before entering, plus a little bit of level grinding.) Knowing that there would be an ambush, I decided to cast Door to the Past before recalling out. I thought that if I gave it a few attempts, I would eventually find a way through the ambush. The ambush is a lot more impressive than I thought (die, archers, die!) and I haven't managed it in seven tries. I would have been good for another seven tries, but I found a nonstandard exit path.

On two of these attempts, I managed to get poisoned after losing. I'm not sure how, but the most likely suspect is an arrow that was still in flight when I lost. The first time the poison was a minor thing that couldn't keep up with my awesome 10/turn regeneration rate. The second time the poison was very effective, and I died for real. I had to use the Blood of Life.

When I came back from the dead, I was surprised to find that Ukruk had appeared. Somehow he managed to spawn again when I came back, but I have no idea how. Since my Door was gone I had no choice but to fight him. Without his guards he was much easier to defeat, and I got the Against All Odds achievement.

I talked to the elder in Last Hope. In the conversation I had options to say "I'm afraid I lost it" and "here it is". Saying "here it is" threw up a lua error (which was pretty obvious in hindsight), but attempting to end the conversation afterward also threw an error (less obvious). Saying that I lost it continues the plot as normal.

When I lost the ambush, I had Paradox Mastery, Entropic Field, Chant of Fortitude, Premonition, and Door to the Past active. Entropic Field makes catching arrows much easier.
