Hey, sorry if this has come up before but I couldn't find anything through the search system. I'm playing the game without any addons, and while it's fun, it annoys the crap out of me when I'm waging war with some race and they decide to give all their shit to a random neighbour instead, probably one that's been doing nothing but research all the time and now has a huge advantage.
Anyhow, I guess it doesn't really matter the motives. I just want to know how hard it would be to remove that option from the trade list. I've read through the modding guide a little but couldn't find any mention of which file deals with trading. Since you can disable tech trading I suppose it would make sense if there was a trade list file like that, in the worst case scenario it's hardcoded into some AI routine I suppose.

Hell even disabling trading altogether would be a preferable option to keeping the surrendering nonsense around.
If anyone has a clue on how to go about something like this, please enlighten me.
