Sorry dude, Mr Tweak (
, funny) can't help you because:
1. he doesn't have to skill to merge those 2 together
2. he's not really a member of the E1200 team. He's a big FAN and secretly wishes he was on the team...but that is another story.
3. I think I've read in the past that E1200 has a couple of the diplomacy features already...but that they did not plan on merging them just yet.
As i've said before...I'm just happy that Korinov is still working on this. Mabe after the Byzantine release in the next patch, they can work on few bugs or mabe improve or add more quests.
Other than that dude...Mr Tweak has tried very hard to keep the interest in E1200 up by researching the tweaks. You'll just have to be happy with that man.
