So please if anyone can do my navmeshes for me all thanks will be appreciated.
Also your name will be included in the credits and the esp file thing.
Thanks Persidon

I have a question. If saving when you have a navmesh crashes your computer, than once someone else navmeshes it, wouldn't you just not be able to save again? And thus not work on your mod, making it have to be complete when they navmesh it?

Try navmeshing, then turn off the navmesh editing, then save. I sometimes had crashes when I tried to save with navmeshing editing enabled.

Or navmesh, turn off editing, then load up a nice small cell. Then save.

Because Gunmaster95 has a point. If you can't save with a custom navmesh, you won't be able to work on your mod once someone else has done it.
