I set my computer aside for several hours and created a 10000 year, standard size world with historical figures culling on. One bug I'm sure of, another that may just be chance or a mechanic to keep the game alive:
1. My region has no name. The list simply says " , Folder: region3"
2. According to my Legends menu, there has not been a conflict (or any event other than new leadership arising within groups) since 1309, at the end of a 726-year war. No assaults/duels/sieges/cities destroyed for 8691 years? I'm guessing it might be related to keeping the game playable (so that not all the elven, dwarven or human factions are wiped out). There are two small dwarven nations left, one large elvish nation, and many humans, but none of them seems to want to fight anymore. Has anyone else created a longer history and noticed things become a bit dull?
Edit: I checked Historical figures, as well, to see if there was some siege or war going on that didn't make it into the Age of Legends entries. The only notables who are dying violent deaths in the last 50 years have been animals attacking people and then being hunted down.
