This has happened to me twice now, so I'm starting to suspect it's a bug. While fighting a monster zoo, I've had to nip to my pocket dimension (the first time to fetch some potions, the second to take a nice healing trip to a wizardland I'd discovered as I was low on health). When I got back, the counter of how many monsters were left was gone. As I've only found 2 zoos, I don't know what's meant to happen when you defeat one, but I've heard that you're rewarded with some form of artifact. If the rather poor item (an elven ingot grinder the second time; I forget what it was the first) I found within the zoo isn't meant to be my 'reward', then I didn't get anything. Both zoos were on DL2, if that matters.
Intended. For... just the reasons you mentioned, so that you can't run away, heal up and still get the reward. (It happens if you go downstairs or upstairs also)
Ok, not a bug but a feature, then? It would have been nice to know that, but I guess that discovering these things is a part of the game. Time to start carrying some potions on me... This thread can probably be deleted.
