Mod conflict or you have EUI installed. Can't help without logs.

Hello, I'm having the same issue here and I see there's no posted resolution so far, though I'm still able to see my unit icons. However the city issue is still occuring for me.

My Mod load order is honestly very light and only includes Il Principe as well as all of your civilization mods and nothing else. I've already tested taking out your Command and Conquer and 202 Nights mods just in case those were the issue. Afterwards I specifically tried with just Il Principe and the issue still occurs so that leads me to believe it's a problem with my installation or something in Il Principe? If you can specify what log file you need I can pull that up but otherwise I'm at a loss here, sadly.

(Edit) I did also clear my mods folder, cache folder and tried a fresh install of Civ V and none of these things fixed the issue either.

Woops, I think the issue is with C&C, try deleting the UnitFlag.lua inside that or playing without it. Will check out, thanks for report

Ok, I did that and I still had the this issue until I re-subscribed to C&C and then re-did what you said again. Then my issue was fixed. I Don't know what re-subbing to C&C did but thank you so much!

having an issue in the diplomacy screen where I can't see which luxury resource I am receiving or trading. I can do it blind but if a civ offers something, I can't see what it is. Also, I can't declare any type of war on anyone from that screen or by engaging with another civ I am not already at war with? any suggestions?
