Well I just started playing FO3 again, after not really playing it at all for like 6 months, only to test my mod. The only mod I have on is MMM. And like 2 of its plugins. I am now suffering from the giant saves that take 10mins to load issue, which from reading other peoples posts is caused by MMM, but fixed in the latest version. However I cannot find it on the nexus, all I get is a bunch of crap other people have made thats related to MMM. Can someone give me a link to the latest version of MMM? Thanks.

Awsome, thanks.

EDIT: Oh crap. Thats the version I have. D: So I guess I'm off to make a thread asking about why my saves are growing in size...

my guess: cell respawn time is probably too big.
if you don't know what i'm talking about that's probably not it

Wait. Saves... Growing in Size?
Since when is this a real issue? They do that all the time. If it's getting really big really fast, then it's bloating caused by a mod. If it's cyclic, then you might be doing a huge amount of stuff between cell resets.
If it's somewhat insignificant increases such as +1 MB for a couple hours of play, then you've got not problem then.

No its growing quite a bit really fast. It went from 1.5mb to 5mb in about 30-60 mins of play, and its taking longer and longer to load. But its also taking longer to load entering new cells, so I think maybe my game is just being weird? The only mod I have active is MMM and 4 of its plugins.

And for the first few hours (5-10hrs) of play my save stayed at about 1.4-1.7mb and now its just exploding in size.

I'd suggest you find a location without any NPC, friendly or otherwise, and wait for twice the time of your cell respawn time. I had an issue like that once which was cleared with this method. I figured something got stuck in a cell and endlessly accumulated data...
