-->Snapshot: How do I undo a land edit on a cell so that a lower mod can edit that space?<--


So I've got two mods that both create islands literally on top of each other. Since I want to use both of these mods, and neither island was very large, I decided to just move one of them. Now the higher mod of the two (the one which overwrote the lower) was smaller and simpler, so I decided to move it north a couple of cells. I opened it up in the TESCS (I'm actually using the extended version of the CS, it's really nice), flattened the old island and built a new one a bit north where I moved everything to.

I'm sure you can see what happened when I next ran Oblivion. I had an island in the north, but my flattening of the old Island also flattened the other mod's island as well. Everything was just floating in the air. There was also another strange error. The little building on the island to the north was bright pink, it couldn't find the texture for structure. Further more, while all the static stuff had moved, the rocks and building and map marker, everything else, like the creature spawners and the door to the building, had not.

So I swapped the order of the two mods. Now I had the island in the south, but no island in the north (with everything just floating in the air). And once again, only the static objects of the first mod had moved north. The dumb door was still floating in place at the south island. However, the structure on the island to the north was no longer pink. It had found it's texture and did not mess up again, even when I experimented with reverting the two mods to their original order (which still didn't move that dumb door!).

What am I doing wrong?!? Why won't everything move? What I want to do is remove the land edits from either mod in the cell of the other mod's island so that when that mod loads after the other mod it doesn't destroy the other mod's island. I also want everything from the first mod - including the dumb door - to move north to the new island. Furthermore, if there was a way to copy and past the actual landmass of the Island north, that would be cool, and look a lot better than the play-doh island I came up with (I've never played with editing landmasses before).

Some help please?!?
