CTD related to government building

I found an ctd playing the Karthardastim campaign.
I'm in war with the Ptolemaioi. They managed to take the City of Lepki, but after a couple of years i reconquered the city, destroyed their government building (Hypercheia Ptolemaia) and repaired my homeland gov building, wich was showen 100% destructed. After i hit the endturn button the game crashes immediately.

It may have nothing to do with your government building. Reload that turn and then don't rebuild your govt building. Check the guide for instructions on how to focus in on the source of a bug.
