I know that in Oblivion, a long cell reset time would cause a save game to become large.
How long is your cell respawn time?
sorry my friend, I'm very noob when we talk about mods hhehe... but how can I do to see my cell respawn time?
Also do you save over the same save each time? Try saving into a different slot, then deleting the first one, and see if the one you just created is as big. Perhaps when you overwrite the old saves it doesnt properly delete the old one first.
hello friend, I have do this, I saved into a different slot, I deleted the previous one, and my new save file was big too...
Sorry for the english! heh
