1.) Approximately one year old.
2.) Just the standard; Great Foxes, Amphibious People, Goamt Cave Centi/Millipede, Giant Cave Crocodiles, Magma Crabs, Giant Bluejays, and so on.
3.) No monsters have attacked as of yet. My only visitors have been a few monster hunters and a human poet, bard, and a Paladin bard.
4.) Medium World, 333 years. I used the pre-seeded world offered in the advanced generation.
5.) A standard elven caravan.
I created a vast amount of wealth using gold, so I believe it may be a creature attempting to attack of some sort. Furthermore, I am using a RamDisk, but I have enough RAM/Space for it, so that shouldn't be an issue.
Edit: It even crashes if I retire the fort and attempt to reclaim it. Something happens on the 25th that the game simply does not like, it seems.
Edit2: Reinstalled the mod. Now, during pregenworld creation, it crashes at exactly year 55. This is the new errorlog:

Edit3: Pregenworld crashes at year 55 without fail. The other presets only crash most of the time.
Edit4: Medium DA World genned, loaded in, greeted with this error:
NULL artifact removed on load x~2000
Edit5: Alright, I believe that your mod reintroduced a certain bug that was patched a while ago:
MOUNTAIN trying to generate musical form without speech or instruments
Impoverished Word Selector

Edit6: Turns out this is also able to occur for actual civs, as well:
