Keep on trucking away
And as a heads up, while it's good to set up diplomacy, usually everyone is on here to try winning (unfortunately, that is now a range from 1st to 3rd rank instead of just 1st in order to get blue tokens). Obviously, not everyone can get the rewards. Most NAPs made are temporary and usually worded by very specifically in order to leave opportunities to fight later on. Sometimes people simply betray with no shame. Other times, people set up their terms so that it's possible for attacks between one another to occur later without making it obvious. But like I said, everyone is here to win in some way. Not many like to place with zero intention of getting something back (like i said, not many, but there are some).
Always keep your guard up and you won't be surprised.
