i had some random player join my alliance right in the middle of a battle and it tripped me out as no invite had been sent to anyone , i closed the alliance and wondering now if im blocking invites .
what is this mess ?

an open alliance means anyone can join ur alliance without u needing to send them the invitation.

if u don't want random ppl to join u, close the alliance, then they can only join u with an invitation from u

thank you
