Yes, that's about what I expected.Funny though that a message was implemented for a situation that should never have occured in the game.
Anyway it's great to see that after all these years this game is not forgotten.
Two funny things about mapping. First time through a got confused by all those maps and made a "side-view" showing how all those dungeon levels connected with each other. Bane is much more consistent than Crusaders, all maps fit together nicely. In Crusaders the maps overlap if you put them together.
Using the Wizard Eye Spell and approaching giant mountain from each side it is possible to create a 3-D map (small cardboxes ;) ) of the mountain. Ever tried that?
