I am fairly early into the game, and suddenly my save size went from around under 10MB to 60MB+. Needless to say the performance went straight to the toilet.

I cannot identify what it is that happened that caused this. I'm running Possessive Corpses AND Mart's debloatifier already, and I am still stuck with HUMONGOSAVES. Is there a way to troubleshoot or remedy this??

There is a thread about that here: http://www.gamesas.com/topic/1356883-huge-save-file-60mb-causing-stuttering/
List all the mods you are currently using over there.

Lets keep this to the one thread please.
