Are you modding BTS or some other mod? Many mods have civic buildings (building is only active with the specified civics).
Rise of Mankind - A New Dawn 2 and C2C for example has this feature (I think KMOD too. I heard many advising to mod KMOD instead of BTS)
BTW I also have a modmod compilation for AND2 (http://forums.civfanatics.com/threads/zns-addons.523763/page-24) and one of them is about civics.
You can try it for more ideas and I also would like to see yours![]()
I'm modding Realism Invictus, but I'm not part of their team. It's just for fun right now as I'm more or less a total learner to modding. My intention is to rework all the civic choices. Now you mention it, it might be worth creating a new civic building, but I really like the idea of certain civics amending the output of buildings that are available throughout the game regardless of the civic. I'll take a look at your modmod but I wouldn't currently know where to start with adding your modmod to RI. But I might be able to cut & paste xml lines for shortcuts! Thanks. You're more than welcome to have a look at the work I do once it's complete (I'll try and remember once it's done and let you know) but it's slow going and depending on the success/failure, might not be completed at all!

It only seems to happen in that specific game. Capturing the city results in this error, capturing another city results in it, skipping the turn and doing nothing results in it (I suspect because another civ conquers a city in the interim), and founding a city does too. However I didn't have this crash before that specific turn and am well in the ADs, having settled like a dozen cities and conquered one.previously.
