I suppose its only trivial (considering the new Client System anyway), but the only time I've had a city "disappear" was when I moved a client ruler out of Kabalaka as Hayastan (I was seeing how far I could march him into AS territory for some reason).

Who knows the mysterious ways of RomeTW.exe ?
