When resolving the Runestone Caverns room of the Dungeon of the Mad mage, I exiled a Plaza of Heroes and an Acererak the Archlich. I played the Plaza first, but was unable to use the plaza to cast the Acererak. The plaza was greyed out, and I could not tap it for mana. Note: I have a screenshot, but did not see where to attatch it.

I confirm, the Runestone Caverns room is "bugged" when we exile a land and a non-land card : We can land but not use the land to cast the other exiled card with it.It should be possible as land does not goes in stack so as we cast the other spell cost the land is accessible for mana.
Also, even it's not an absolute argument, it's possible in Arena.
