I messed up a cell's navmesh (wilderness, -10, 0) and wanted to revert it back to its original state so using FO3Edit I deleted the cell. It wouldn't let me delete only the navmesh so I deleted the whole cell and decided to start again since I hadn't done much work on it.

Only now whenever my mod is loaded I can't go to the cell without CTD =[ It works fine without my mod active, but with it, the game just crashes. I just want the cell to revert back to normal please =]

Any help appreciated, thanks in advance.

Navmesh in an exterior cell when altered alters surrounding cells as well.
Pathing is one such example.
I recommend you look for these and wipe out the unintended changes in those as well.

You can also create an esp where you modify only this cell and merge the mods. It will replace the defective one.
But it may take several finalizations before the cell connects well to the adjacent cells.

Thanks both =D Michele, you were right about it affecting more than the one cell. Working perfect now thanks :celebration:
