Zandelf's Crimson was in Cave of Eternal life and spawn Warbot, got key, gem and getting xp. Maybe something to look into.

Thanks for reporting that, Dark. I did recently modify the coding for the cave so that persistent creatures would not respawn automatically if they were summoned in the cave. Otherwise, I'd have had a situation like the white dragon in the Templar Output who kept respawning indefinitely. It appears I have somehow damaged the other part of the script that prevented creatures in the cave from giving XP and loot.
