I patched Conquests to 1.22 and started a new game as the Celts. Regicide was not activated. I occupied every last English city, but they're still around! To make sure, I made peace and forced them to hand over their World Map, just in case they had remote city somewhere. Found nothing. Then I went to my Embassies, and it showed them as having no cities to build embassies in! YEt they were still alive and paying me 1 gold per turn! Why won't they just die?
