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.

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 ?

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.

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** · 04-29-2007, 01:02

yeah, missions could make sense in this context too.

I've always had a random crash issue on my big map and thought it was somehow mission or possibly event related (partly because I hadn't really edited the missions) and because it seemed to be delayed if I got some sort of event early on (eg candidate for adoption, marriage etc). Makanyane then tried with a smaller map but didn't seem to get the crash so could still be pathing.

I tried running the game automatically using the AI's setup but this used to show the map on the whole screen and then just crash so I didn't know what turn anything had happened on.

Well missions aren't all there's to it. I removed all missions and all events, but I still get crashes (I think less frequently, mind).
I also made the map smaller to a size of 50 pixels in regions, it has 9 rectangular regions 8 of which belong to england and 1 to France.
I still can't figure out what crashes it but it always happens in the Rebel turn. It doesn't happen in vanilla, does it? I'll try an auto-pilot test.
