Pvp matches kingdom doesn't match

After a match in PVP I will get the message ‘kingdom doesn’t match’ and numbers 3014 no rewards and given and it’s now happened every game

i got this one time on a pvp… wonder if the player you were playing changed their home while you played?

It’s happened to me numerous times in the last 24 hours, also after one time I had to close the app as my PVP wouldn’t load at all. It’s not really a great issue its just frustrating
