Can't progress to Exploration Age due to Mod error - can someone diagnose?

[bismarckian]

Hello,
I've been playing as Assyria but through multiple games Civ continues to crash when I attempt to get to the Exploration Age. I'm running a number of mods, and am not finding which mod is most likely causing the error. Can anyone tell me what mod is crashing? Here is the database.log:

A list of the mods you're using might help narrow it down, either that or disable the mods one at a time until you find the culprit.
