Can't find any of my friends

Hi,

I can't seem to find any of my friends I've asked to play the game, They are all from UK but for some reason I am unable to locate any of them.
Any help truly appreciated.

Are you sure you guys are on the same server? Aka 'Newfoundland'?

Good point, didn't think of that. Thanks

Can you change server without losing your progress or do you have to start over?

Start over.
