CTD in the year 236

[Shorebreak]

I have been playing a new campaign with the Romani using BI 1.6, EB 1.2, city mod 5.1a, and the EB for BI mod, and have not encountered any problems until now. I hit the year 236 and when I end my turn, the AI turns began to cycle like normal until it hits Lusotania and the game crashes. I have also installed all of the 1.2 fixes to no avail.

I also just started recieving this error msg:



Does anyone have any idea what could be causing this and/or can take a look at my saved game?

Here is a link to the saved game file: http://www.savefile.com/files/2144995

I appreciate any help or input! Happy 4th!
