I'm not able to reproduce the crash with your save. I let it run for 10 mins at game.speed = 10 and it seems fine.

But there is one mod "Intellegent enemy", which caused the game to have a massive lag spikes. It seems make enemies to run all over the places. Maybe it somehow break my enemy group?

What if you disable that mod and try to load it?

I'll try, thansks

I forgot to update, it works fine without that mod
