Here is a bug. I got Sunset Invasion event, after that i got event about Aztec Invasion, Smallpox and Sweets from New World. Aztecs got North firstly then got The Rock. Now its their third invasion, this time of the Reach. They use 177k doomstack, this just ruined the game TT.
I'd think that doomstack would get eaten alive by attrition before too long...
