We are actually playing on the com2 and we've met a situation. We have just learned that when a wonder reach lvl 50, we can't invite any player in the kingdom anymore.
This is kind of a big problem, first of all we were going to merge with an other ally so there is actually a whole alliance who are alone, without kingdom and we can do nothing for them. Second things if there is a player who chief and are mistaking attacked by the king, he can't be invite anymore in the kingdom...
I can understand this rules but it could be at least effectif only for the kingdom who reached that wonder to lvl 50 and not for every other one.
Because of this there is a lot of player on these server who are without kingdoms and can't join an other one so should they keep playing alone ? they can't see any messages of the kingdoms or even sell their treasure... this is quite unfair for them. A lot of them are actually under starvation because of this and lose their pleasure of the game. There will be probably a lot of delete if it stay like that.
And by the way, we checked the rules and saw nothing about it on the forum or the wiki, we just knew after after sending a message to the support...
I think this rule should be change... Don't you agree ?
