After the End Fan Fork
Holy Columbian Confederacy Succession
I'm playing as the King of Florida in 2858 (formed from the Duke of the First Coast, so I didn't start off in the de jure HCC but the Kingdom of Florida has since de jure drifted into the empire), and at one point I became an elector. Although I eventually got that dude elected Emperor through a ton of assassinations, when he died shortly thereafter I lost the electorate and was not able to become Emperor again before I lost my claim, so now I can't even install myself through a faction. Now that I'm more powerful and technologically advanced enough to reform the Empire to primogeniture, I can't seem to find any information about how electors work in this mod. Can anyone help?
