Well I have the same problem. For me the map usually crashes on the rebel turn (I expanded the map a bit and added more provinces). I don't have any theories yet as to what causes it (and in fact there are probably multiple reasons).
I noticed that it sometimes gets worse if you use different ai settings so one of the problems could be pathfinding. I really don't know.

True it might be a size thing causing the error through pathing but as the remainder was sea I'm not so sure. I don't know whether there is something tied to missions or one of the random 'comparison' events (ie you're the biggest, richest etc type things) that may cause it as there's only one province one faction to compare. However I've had similar random crashes where I have a big map and several factions so not sure.

Spent some time this afternoon trying to work out where it was happening and all I could get to is that it seemed to occur regularly between the top and bottom of these log issues. The last definite line to appear was the top one and the only guaranteed line if it didn't crash was the last one - the others being tied to events etc).

We're now trying to set up some scenario's to test on a smaller map which may point to either pathing or memory. Although even in Vanilla I used to get odd crashes early on so I don't know whether there's still a bit of a bug problem... I'm pretty much out of ideas on this one.

I think it is pathing somehow. In my version i've added a chunk of land but not much and it crashes now and then. Used to crash on the first end turn every time when i had one particularly huge region. Maybe pirates trying to find land on the other side of the map or something silly like that.

It is starting to look more like it could be pathing or something else related to size - spent most of yesterday working up a smaller map, reduced Alpaca's base map to about 200 pixels square map_regions, and added land mass, regions etc., but without changing any non-map files or set up. That one hasn't crashed at all yet. (touch wood)

The earlier versions we were having trouble with were 510 pix square like the stripped down map, though with lots of land and regions, they would still have failed under the old landmass problem, so there could be some vestige of that still around ?

[nikolai1962]

The thing about the pathing algorithm is it needs to store information on all the tiles it has checked while it is executing. It has an array of all the tiles it has checked and rejected and an "open" array of possible paths that it gradually goes through till it finds its goal. On a large map this can apparently lead to a huge demand on memory. On land, they can get around this by region-hopping but i don't know how they'd deal with it with a really huge sea. That's why i was thinking it might be pirates. Could be a red herring.

[alpaca]

Yeah you may be right. I also believe now it's got something to do with missions because after removing them it seemed to run more stable.
I'll remove pirates next to see what happens.

[nikolai1962]

yeah, missions could make sense in this context too.
