Alliance relocation

Hi all,

Few days ago, we move from K469 to K482. I try to change the kingdom of the alliance but I have an error message: "impossible de changer vers un royaume étant plus ancien". In english, if I translate it, the error message seems to be: "Impossible to change to another kingdom as you are in an older one?". Do you already have this error? Do you know how to solve it?

Thanks

Dark
