Current questions and answers regarding the map editor.

I placed the "Dungeon" tiles in the abyss on the map (the ones that are hidden in the editor). I encountered the following bug: If a player reveals the fog of war over even a small part of the abyss, and then saves and loads the game, instead of the abyss, the landscape of the upper level of the map is duplicated – rivers, soil types, irregularities, and so on – all of this is displayed instead of the abyss. This doesn't happen as long as the fog of war hasn't been lifted from them. I've seen abyss tiles on many maps – has anyone else encountered this?
