ToME: the Tales of Maj'Eyal

Edit: Hmm there's an event that wipes the map(west) and makes it unexplored again. Along with it all newly spawned dungeons disappear. That includes mage city, tempest peak, graveyard, bearscape etc. For me it happened after daikara... I think it happens when you complete all tier2 dungeons ? Or maybe rat lich dungeon... It happened again on a character that did it and noticed that dungeons are missing.

edit: nvm doesnt seem to be tied to caldera
