That's why I commented...I don't think it's caused by ICV but rather by a faulty install. Are you using the version of EUI provided with the installer? Have you deleted the cache and modsettings folder files after installing?
Maybe try removing all mods and also the bc1 DLC (EUI) and then reinstalling (don't forget to delete cache).
Same here though I'm using quite a few mods and also the 30-11-18 version of VP. Also, everyone on my continent has "territorial disputes" with me even if they're far away and don't share borders with me. That could explain part of the high prices but it doesn't explain why they all want my territory when there's other civs right next to them. And Polynesia, who came from the other continent and is the only one without the terr. disp. modifier still has pretty high prices, though lower then the others.
