How many turns does it take (or where in the interface) do I check to see when a promise no longer holds sway? For example. Scythia asked me to stop converting their cities, and I refused to make a promise. I keep accumulating 25 grievances if I use a charge on a missionary / apostle. I scoured the interface, but couldn't find how many turns left until this promise ended. I scoured Google and the only answer I could find was '15 turns.' I waited well over 15 turns (21 turns), and yet I still receive grievances when I try to convert their cities.
