Hi guys, this might be me just being really stupid, but every time I open up the Creation Kit and load a mod I've been working on (a small dungeon) a whole load of stuff just disappears from the mod, i.e. walls. doors... basically everything structural that I have placed.

If I'm just being thick and this is a really easy issue to fix, then just say so (I'd like to clarify I'm new to the whole making mods thing, this is my first one).

If anyone has any ideas at all on how to fix this, then just fire them up here, I welcome any help whatsoever.

Thanks
