Game crashes after 3ish months

So yeah the title says it all. I don't know what's happening. Never have I ever gotten a single crash. But yet, it's my first time going this far in the game. the year is 8389 and I'm playing as a summer islander in Omburu. great game so far pretty much made the place white haired after intentionally breeding with the essosi valyrians. As that being said I should return back to the topic yes. I'm pretty frustrated and I don't know what to do about it. I suspect it being some of the submods but they're updated to 1.9 I'll list them:

Agot more bloodlines
Agot more buildings
Better faces

bigger interface - note that I didn't install this properly. I threw the interface folder into Agot mod folder which replaced and added some since my bastard ass couldn't care more since a proper installation didn't work. But yet I'm sure that can't be the problem?

That's all my sub mods


I still get the cheksum problem though and I installed the game via a .rar folder which many don't do so I don't know. I'd like to save my file since I spent a bit of time with this save and I'd like to know if it's possible that it could be fixed.

That being said I thank the mod creator for making this lovely mod!


Update:I disabled all sub-mods, but the crash kept happening after 2 months on day 22. 


Update: apparently the game started to lag every month on the first day, like a 10 second lag.
