Did you change the default number of civs/city states in the game? Votes for victory are determined by map size not actual players at game start, so if you've dropped the number of people in the game you might not have enough.
I loaded the Huge Earth Map Mod. And I did decrease the number of total civ's and city states in the game. I figured it would know enough to compute whatever majority was needed. Soooooo, I guess my mistake.
Thanks for answering.
