Alliance union

how does an alliance uniln work....i joined my friends alliance union invite but I lost all my song I had when I was in my own aliance (I wS the leader) I was jw if the person that merges to the invite alliance if thats normalm

Whoever invites you, and you accept -- you transfer all AP to them and all your members are demoted to provisional rank. So it's best to do whichever has the better built tree, and that's typically the more active alliance in this case.

yea was curious about that too. If I lose all my songs that would be really stupid to even bother doing a union with.
