This issue with my game really has me stumped. I have played many hundred's of hours of civ5 and this is the first time I have come across this problem.
I have only completed 100 turns and one of my cities has just completed building the market at the conclusion of the turn and is now ready for another production project. The thing is I can't choose another production. The next turn button is saying "Choose Production", but when I click on it nothing happens.When I open the city screen and try to choose another production task from there, nothing happens. I can keep clicking the "start another production" button, but it doesn't do anything. I have cleared the cache. That didn't help. I have restarted playing from a couple of autosaves before and played a few turns building other things besides the market, but when I do eventually build another market, exactly the same thing happens. These are the lines written in the lua log as a result of me clicking on the Choose Production button.

I think if I was to start a new game using the same mods the same problem will crop up again once I build a market. I play with quite a few other mods including CPP, CBP, but not with EUI. I would appreciate help in determining in which mod the troublesome 438 code is located. You could help me to diagnose the problem on my own or I could give you a copy of my save game for you to do it for me. I will let you knowledgeable people on here advise me further. I really enjoy playing with the CPP and CBP mods and thanks for all your hard work and support.
