Not as far as I know. None of the official maps has it... I think.
So, I remember someone said something about dungeons being unusable? Is it still the situation? I hope not, and I havent encountered any problems with them in my new map...
Oh, and you guys, check this out. I made this dungeon-thingy (mentioned above), I managed to do a quite big complex. Theyre really useful for adding alternative, but dangerous routs to enemy. My initial inspiration were the AvP jungle ruins, but I decided to stick with more medieval setting.
