All 4 One Event

So I created a new character and my friend is a "boss". My main character on my account is also a boss.

He can't invite my new character, for some reason. Anyone know why? It just says he's not allowed to use it or something..

I had the same issue with recruiting my friend as well.
Can't be certain, but I believe you have to recruit someone who has made a completely new account (with a new character) for it to work.

Going to try it out in a hour and make sure though... If not, the only other reason it could be is you can't have a Boss and Recruitee on the same account... or rather it's just glitched. :S
