I have a problem understanding your problem.

Is it that the option is in Spanish, or something else?

I do not even speak Espanol if the problem is not under standing the option it is " declare war on Baratak Grove. 

What is i18n? 

As for the option being in the "wrong" language thanks for the report.

Yes, the problem is that their code shouldn't be mixing Spanish text in the English version of the game. Therefore this is a bug that I am trying to report.

I know exactly what it says, I was pointing it out as a bug so that the dev team can fix it. I guess this isn't the appropriate forum for this?

The i18n is Dev shorthand for Internationalization, ("I" + 18 letters + "n").  Are you on the Devteam gypsy2299 ?

"my Spanish isn't very good" was my attempt to keep the post jovial, hence the great big smiling face 

No but am a mod on other Gal Civ forums and this is the place for bug reports.

I asked my question as it was unclear what you were asking and nowhere did you indicate it was a bug report.

I asked just what the SD crew would have so when they get back Monday or Tuesday they would know.

Monday is a US holiday so them being here on that day is not a sure thing.

That's interesting.  The game this occurred in was one I started in Vanilla GC4 and after roughly 100 turns, during a break, I did download some Civs from the Workshop, couple of days later, (still haven't started a game with any of the new Civs yet) the language prompt is mess up.

thank you guys for posting about this. If you don't mind, do you have impacted save files, preferably set to the exact turn that the event shows the incorrect language text by chance?

It happened again, in the same game, in a slightly different way

But this time I grabbed some pertinent save files

The save I named was immediately after the bug occurred, and I added the 2 previous Auto Saves

Hope these will get you on the right path.
