So has any one else seen this message?

I  am trying to move kingdoms during the battle, had no problem previously now I am stuck. 

O.K. 

so know I have an understanding of the situation but remain confused.

I have just tried to do the same thing but with a different kingdom account and got a different message.

This message said  you have to go back to your own kingdom before switching to a different enemy kingdom.

I could be wrong but  I am sure I didn't do this previously. I think all I did was click on the kingdom with the new feature and jumped there.
