My friend and i have had this skyblock co-op profile for 3 years now. We logged on to play today but when my friend entered skyblock he was put in his solo profile. He didnt find the co-op profile that we play on. I could see that he was still in the co-op profile but he couldnt. I tried removing him and adding him back but he wasnt recieving the invites that i send. What do i do?
