for me it looks like the merge will not be in balance. and i think its becouse you wassnt able to select the most powerful kingdom. but the secound most powerfull was ok. that ended up with 2\3 kingdom all ready for this merge.
next merge. 54-> please do following:
when you enter. you must select the [u]weekest kingdom[/u] as lord of a noble house. end of all the house member have that kingdom as recomended.
if member want go to another kingdom they must simply wait unthil the kingdom they want is the weekest.
