I have the option to have great prophets found religions turned on. Some turns ago, I researched Ngaiism, but decided to use the great prophet I got to build the wonder for another religion, with the intention to found Ngaiism at a later time using a great prophet obtained via normal gameplay. However, last turn France somehow managed to found the religion! Since they're behind in technology, there's no way they researched Ngaiism too (and the tech description says that should be impossible anyway). I can only assume that they got a great prophet, and he was able to found the religion despite the fact that France wasn't the one who'd researched the religion. Is this intended behaviour? If so, should that be spelled out more clearly in game?
