I had an issue where custom civs wouldn't have the diplo marriage ability. Here's how I fixed it.
Unsubscribe from the diplo marriage mod and your custom civ mods. Then load CIV 5 (by load CIV 5 I mean just get into the game-starting menu after you finish the mod-loading screen in the game's menu)

So anyways load Civ 5 after unsubscribing from the custom civ mods and diplo marriage mod,
then close Civ 5,
Then, subscribe ONLY to the custom civ mods. Then load CIV 5 again,
Then close Civ 5 again, then subscribe to the diplo marriage mod, anddd that's it.

@Azathoth Same problem

Are this mod work only on vanilla city-states? I using city-states expansion 1&2 mods

This is great, but for some reason this seems to stop working if you use Global Warming mod and/or city sprawl. If by some miracle you see this, can you explain why?

Has there been any new updates? Will the mod come back any time soon?

Very sad that this mod no longer works, if anyone could possibly remake this mod, or even if the creator could update it even. I'd be incomparably happy. RIP most my mods.

this mod was great but has stopped working for me also

I'm sad, this use to work, but for some reason it won't download and install. I loved this mod when it was working.

I have never seen this mod work. I play GnK w/ a few other mods. Are there any mods that nullify this?

I was using and enjoying this mod, as it makes expanding your empire quicker and easier. However, recently steam did an update and it stopped working. Have you looked at this at all?

can you marry with another major civ?

i changed it from 15 to 3 turns for ally to test it it would work still will not give me an option to marry them

If another civilization 'takes' a citystate from you (say through a coup) and you immediately buy it back the next turn, does that still reset the turn counter?

im pretty sure i was an ally for more than 15 turns but still nothing

Remember you still have to be their ally for so many turns and then the option will appear

i dont see any option to marry anyone in the city states and im only usingthe serbian mod (so no mod conflicts) and im playing with the danes so i dont know whats the problem pls reply as soon as u can and i hope i didnt miss spell too many words

okay because I'm using earth 2014 so that make sence

Possibly....are you using any other mods with it? Sometimes other mods can cause a problem.

maybe because I'm on Macbook pro

it doesn't

Mod should work for all civs.

America

What do you mean by "OTHER civilizations"? JakeySnyder

can you make this mod work for OTHER civilzation? please

A little help for colonize the new continent

I'm not sure what mod that could be though. What mods would conflict with yours?

The odd thing about it is that whether or not it works is completely random. Sometimes it does, sometimes it doesn't.

Are you using any other mods along with this one? My guess is one of them maybe not compatible

I keep getting this issue where the mod sometimes works and sometimes doesn't. It seems completely random. You know what's up?

Everyone is going to have their own idea about what the Austria UA should be now. But my feelings are to leave it as is.

You can always change this yourself in the files themselve and give Austria any of the existing traits or make a new one for them.

So I managed to get a super powerful and awesome economy as Rome on a TSL map, and think that it's pretty cool that I'll be able to annex my neighbor Genoa and actually unify Italy without warmongering against city-states for once through diplomatic marriage. My only beef with this mod is that Austria's UA is now not very useful and also that the UA doesn't seem to reflect any of Austria's history. Maybe Austria could receive a cultural UA instead?

I think it would be col if you could do this to civs that you are influential with, or have been in a declaration of friendship 5 times, or something. It would be a nice alternative to war when trying to get land, because if you take one city every other civ is now your sworn enemy. Just thinking outloud.

Its due to mod load order. Unload all of your civ mods and this one, exit the game. Restart the game check THIS mod to load first then your added civs next. If you download new civs you must do this again or that mod civ will not be able to marry.

Has there been any progress on getting this mod to work with other civs? I'm using the miods by [SSU] jyengyamg and would really love to have this mod available for use.

can this be used even though i dont have gnk?

could you add a version where the mod "dalmasca civilisation (bnw)" also can make use of your "diplo marriage mod" would be really great

I am going to say it is a conflict with another mod you are running. Sometimes a mod that creates a new civ or mods any portion of the civ traits could cause it to override this mod. I would ty it without the other mods enabled and see if it works then

I haven't been able to marry a city state yet. I've been allied for over 15 turns, have enough money, and am playing on a quick game. I have other mods running but the option doesn't even appear.
What can I do to fix it?

Cant download. Can you share with your mod on civfanatics?

Ah ok

Austria now get a different UA.

Soooo this ruins austria UA if you have austria

is this compatible with the CSD (city-state diplomacy) mod?

i have an issue with this mod it used to work perfectly but now i cant marry anyone but the AI can?

This renders the merchant of venice no different from a great merchant, something for them too maybe?

Could you make a version of this mod that is compatible with BNW?

Ravencrow - Currently, you must load this mod AFTER a civ, if you want that civ to be affective. Sometimes, you must completely remove Diplo, install the civ, then re-install Diplo. It's irritating, but it's worked for me thus far. I do not know (having no modding experience myself) if there is a way to fix this in the code.

It's possible to include modded civs ? I really want to play Phoenicians with this mod, but the option won't show up in the menu

Would be cool if you could marry other civ leaders, instead of just city-states

how can i check how long i've been allied with a CS for?

@ I Am A Noob

Currently I am going to keep it where it is....the thought behind this is that you have to make a significant sacrifice in order to use this function....this way it become a serious decision within your strategy and you may have to neglect other things in order to do a Diplomatic Marriage. If it is too easy then it can be abused by both player and AI.
