Unfortunately I don't think that is the case, if you code a trait wrong it just doesn't work as opposed to causing lag, if anything Congenital Overhaul will make your game less stable due to the inheritance scripts and more traits the games has to evaluate in events as modifiers.
That is what I don't understand ninja, but the game is more stable

with it.
And the checksums stops changing, before that the checksums keeps changing after a crash.
It should be a lot more unstable with that submod that eats more resources cause of potraits, events and new traits.
Infact that submod made me enable the african potrait dlc again (had it off in 0.9.1 and 0.9.2 to increase performance)
So instead eating more resources and increasing the frequency of the crash, it is causing less.
One crash the whole day with a war on stepping stones (could be some boat issue) AI is even summoning 1 troop levy again!
I really don't know, anyway awesome work on the valyrian colonisation submod ninja
Can you make Valyria a 7 spot ruin colonisation.
Also reforging the valyrian faith, the head of a region should have a holy order.
Am trying some submod it makes 0.9.3 more fun
Love the whitewalkers potraits especially if they are given valyrian clothings.
only the shadowbinders females should have muslim emperor tier clothings, instead of that ugly mask
They would have veils covering there faces.
