I don't know if you've gotten this answered yet or not, but it sounds like you may have the issue I had when making my first dungeon. That being: many tiles did not render and as such showed up as black space that the player character would fall trhough before respawning back at the original spawn point. I was able to fix this through some determination and, mainly, deleting the problematic tiles and placing new ones in the dungeon.
I haven't had this issue yet with the imperial interiors, but had a lot of issues with the nordic set and one with the green caves.
