Issues:
it says "Processing Turn for Korea" (the nation im playing) at all times at the bottom of the screen

When I go to discuss with another leader the options are a stack of
"Perhaps we can offer you something to keep this from getting out of hand." repeated eight times, then "If you're smart, you'll stay away from me"
and then "I hope our friendship remains strong" (even if you're neutral or at war)
and lastly the usual let us discuss another leader button.
Selecting any of these options instantly declares a surprise war on them lol

and the diplomacy tab now just displays Washington (I selected all the civs at the start of the game and america wasn't one) says their status is that theyre on Team 1 and their Power (????) is MIDDLING.

OH NO DIPLOMACY IS COMPLETELY BROKEN YIKES

Never mind I managed to kill them with a bit of save reloading but you best make it so city state start locations cant overlap

uh city states seem to be able to spawn on top of each other and even build their cities on the same tile which does all SORTS of wacky stuff to the game. trying to kill either or both city states with IGE just breaks IGE (IGE.CityBanner.lua:172: attempt to index local 'city' (a nil value)) and the offending city states come back the next turn.

This was Singapore and Malacca occupying the same hex btw, with only Malacca able to be interacted with

So you were responsible of lessening Rhye's headache on coding RFC.
