mod or savegame problem?

[RDV]

I've 99% finished my mod but a problem has just developed. I've been very careful when testing to disable the mod after testing and not save my game with the mod active. However when I load any one of our main savegames it crashes to desktop instantly when the mod loads. I have a savegame where I'm saved right outside the cave at Helgen at the start of the game, level 1. If I use this save the game loads fine and the mod works fine?

Every time I make a large change I make a backup saved in a different folder, I've tried using really early backups that I know definatly worked with my main savegames and they no longer work either. If I disable my mod Skyrim works fine. I've even tried removing literally everything in the mod (because to start with I thought I'd got too much stuff in it) and it still crashes.

I've been very careful when making the mod that I haven't opened or changed anything that's from the original game (I mean in the editor there are no stars next to anything except next to those things I have made myself, I have checked and double checked this. there is one exception I've connected the mod the the gameworld in a wilderness cell, a door, 2 rocks, a chest and a bone rattle).

 

Is this as I fear more a problem with the savegames than the mod? perhaps because we've walked through the wilderness cell in the savegame and now it's being changed it doesn't like it. The savegames are about 12mb so I don't think that's over bloated to cause a crash is it?

Or is this a problem with the mod? I'd like to release the mod very soon but do not want it to break peoples savegames. Is there some way to find out for definite what the problem is? Or someone far more experienced than myself who wants to test it and make sure that if I release it it's not a savegame breaker.

 

Thank you.
