Hello, My friend (@Jamo7777) and I have experienced a problem with the skyblock island invites. Whilst we were playing, jamo7777 did /island and it created another island for him, which made him leave mine. Now when I try to invite him again, it says he is already in my party/island. He cannot place, break or open any chests on my island. It would be appreciated if someone could help us with this problem. @CollinPotato Thanks.
Maybe try /is leave for him as he's not on your island - Just make sure he has nothing on him. Then reinvite him.
We have solved the problem! I did /island leave and then invited him again, surprisingly it worked Thread lock request. @smartguy27
