i get crashes when saving new world maby thats the reason i cant load it later. Is it possible for someone to upload somewhere already created world? just save folder or maby whole game folder, dunno.
Using a script I attempted to generate 60 large worlds, and only 20 completed successfully, the rest crash during the save. I repeated the test with the medium setting and in that test I got 48 successfully saved worlds. Notably I haven't gotten any crashes with pocket worlds, obviously whatever bug in the mod is causing the world gen to crash is less likely to trigger on smaller world sizes.
If anyone wants one let me know, here's a dropbox album with the world maps.
Now to try out DA without DFHack and see I still get crashes during the game.
I've not experienced any crashes on the Windows version during world gen in a long time. Including with DFHack on.
How many years old are these test worlds? Old large worlds are more prone to crashing, probably due to memory/space constraints.
I recommend turning off DFHack during world gen if you experience crashing. However, this is not a bug with Dark Ages or something that I can correct. DA pushes DF to the limit of world gen and any complications can potentially destabilize it.
I ran your saved game with DFHack off for about 45-minutes with no crashing. So it may be possible to just turn it off-and-on as needed.
