cores... I just got an Intel i5 that should outperform this piece of shit I have now by a huge amount. and 8gb of RAM to support the new motherboard. I
knew RAM had something to do with the crashing but everyone assured me it was purely the processor.
Also I find it odd how, during world gen, the game will reach 550-600k K of memory usage on the windows task manager screen, then spontaneously drop down to the baseline and ramp back up. Happens around year 130 or so.
On the real topic: I can only ever gen large worlds to year 200. I would love to go further, and am hoping the ram upgrade, which doesn't max out my motherboard, will let me reach 4-500. The best way to deal with the kobold issue is to just go to raw/objects/creature_standard.txt, search it for 'kobold' (ctrl-f to search for keywords) and below the tag [UTTERANCES] in the Kobold entry you just found place [NO_EAT], exactly like that. Then save and exit and generate a world. It'll work on a pre-genned world, but they'd already be dead anyway.
And if you can't generate a 1000+ year history, search for 'dragon' in that same file, and when you find it search for BODY_SIZE and select the one that reads [BODY_SIZE:1000:0:25000000], and change the '1000' to anything to less than the number in years you intend to generate to. This will force them to be the adult sized by the time world gen ends.
