Hi I've noticed that some of the boss attack links are greyed out in my Social Settings page. I admit some of them are probably because I'm already in those fights but not all. Here's a snapshot of the problem ( ) As you can see, there is an entry for "[MLC] Searching4MyLostShakerOfSalt" I can't attack him because the "Attack Boss" link is greyed out. I'm definitely not already helping him as you can see from this ( ). I think this is a bug.
Could be the boss is already dead or has the max # of helpers already. From your screenshots it does not look like max # of helpers has been reached though.
