Hi! I've also heard of this mod for the first time in Marbozir's video, it seemed really cool and immediately after the first one, I've downloaded it and played it.
I've played with the Guptas, and so far there's two problems I'm having with the mod:
First, a really minor issue, whenever I get the Gupta unique ability that gives me a one-time boost of science, There's two error pop-up windows telling me I don't have the art file for it or something, and the icon for the event, in the right side of the screen, is completely red. It doesn't really affect the gameplay tho, so it's not that problematic.
Second, still a minor issue, but more problematic than the first, it's that the buttons on the top-right side of the screen, where the diplomacy, culture, economics, etc. are supposed to be, just aren't there! The only button is the diplomacy button, but it's unclick-able. I can get to most screens easily tho, with the F keys or whatever, but the only one I can't get into is the one added with the mod, about some special decision I can make. The game notifies me every few turns about it, and I have no idea how to access it. Nevertheless I can keep playing without too much problems
DIPLOMACY MENU "ISSUE"
To the people with the issues about diplomacy menu not working, you'll have to go into your civ 5 folder in steam, go to DLC remove ui_bc1 (for EUI) otherwise those menus will not visually show properly in this mod.
Is there a way to get this to work in multiplayer?
Woops, didn't notice the comments on this page. I'll try that, hopefully it'll fix the second problem.
