My game (with MegaMod 8) is crashing when I reach 2000-3000 population

[Andrei04DM]

It happened twice to me now.
When I get to a really big population, I get a fatal error and game crashes and can not use that save anymore. Tried using the autosave, but it still gets to the point where it crashes.
I can still start new games, I jsut can not move forward with the save with the big population.
I'm using MegaMod 8.
Attached the crash dump. Can someone please help me?
