I just created a whole new map with the Map Editor by selecting "New". This blanked out the map with all water tiles, and I created the land mass. For some reason, and I've seen this in other mods, some terrain types have dead spots - you can't click to move there. Particularly, it seems Steppe tiles do this, and I've noticed some snow regions do this too. If you teleport there, you can't move out. Does anyone know why this is, and what can be done to fix it?
