Troll caves mean trolls. They might not be in the cave, but they sure as hell are lurking around close by. You might have missed them. Trolls kill wolves very easily unless you have superiority in numbers. Not sure how many wolves you need to kill trolls reliably.

Might have been possible for the op, but 17x 1 stars & 3x 2 star wolves vs one troll? I doubt a troll could even do something like that. I'd chalk it up as some sort of bug I'd say.
