Something appears to be messed up in Castle Mistmoore 3 on Nightmare. When my level 90 Ranger goes there, he gets the repeatable quest and kills the yard trash. Then Xicotl appears with his pet and one add. So far so good. However, the princess never shows up, so if I kill Xicotl, stop, and then ask for another mob, I get Xicotl again. And again. And again. Which, of course, can be used to farm items.

In addition, one time something weird happened. I am not sure what the sequence of events was, but I think that when I ported to the zone, I never got the quest. Instead I got Xicotl right away and got stuck in the Xicotl loop. On rare occasion, if I hit "1" a bunch of times, dismissing Xicotl and summoning the next mob, I would get another named, but 85% of the time it was Xicotl. Also, he **always** dropped unique items, which was even more exploitable.
