Summary0005633: TITLE Changes Large Region History, Also Something Else Unknown
DescriptionI have a large region world generated in 34.05 which I like. It was generated randomly using the standard LARGE REGION paramter set. I exported the generation parameters and tried to reproduce it, and I have failed.

Existing world:

   130963 Dwarves
   66407 Humans
   141128 Elves
   156821 Goblins
   2441 Kobolds

   Total: 497760

With title PLANE OF SOULS:

   151251 Dwarves
   76379 Humans
   143451 Elves
   236856 Goblins
   2301 Kobolds

   Total: 610238

Two runs of the above generated identical worlds.

With title LARGE REGION, exactly as exported:

   142325 Dwarves
   63612 Humans
   141294 Elves
   202481 Goblins
   2355 Kobolds

   Total: 552067

This is not the same as the original, nor as the one entitled PLANE OF SOULS.

I tried generating a pocket world and reproducing it with the title changed, and that worked. The region size seems to be a factor.

This morning I tried generating a completely new large region, this one with zero vampires and full history (no culling). Although the history file appeared normal, when I went to look at the world in legends mode only a little over one hundred of the historical figures were listed, and nothing in other catagories. I did not try to play in that world so I don't know if I would have got every migrant listed as having zero relatives. I can do so if the experiment is useful.

When I went to look at the world definitions I saw that large region is the only one that has culling historical figures on by default. I am guessing that the problems with large regions is a known one.
