I've been living in your saved game. I appreciate the Frogboy. I don't know how CariElf would feel about things though.
Anyway, lots of interesting things here.
So, why do games crash during autosaves? The answer: memory fragmentation. Save games allocate 50M of memory to do their thing. At a certain point, with so many things being allocated and deallocated you eventually end up with the largest piece of memory being 20M even though there's nearly a gig free. So voila. Crash.
Now, hwo to fix it...
Thanks for working on it and sharing the info. Do you know why the debug file would show 16x16 when the map clearly isn't that? Is the game somehow treating the map as 16x16 and the debug is correctly showing what the game thinks or is the game correct but the debug is showing incorrectly? I was wondering if the game may have been allocating too much memory due to misinterpretation of map size or something. Just curious really. Is there other information I can provide in future posts that is helpful at a glance?
On another note I think next time I run a new game the first male child of you and CariElf's matrimony will be named Lord Xia and he'll come with a pet pony.
