Again, I am reporting something that happened over a year ago. A bug that had taken my island and gave it to my coop, it has been bothering me ever since. Is there a way to give it back to me? Thanks.

 

I have moved this to help since it is not a bug/exploit.

Can you please be more descriptive? If I am hearing this right, your island (the owner of the island) has been transfered to a member of your coop? If so, the new island leader of the coop will have to re-invite you. All the coop members would have to leave except you, and you will become the leader. You can then re-invite the players that were in the coop before. (Remember, when you leave/restart an island your inventory resets.)

 

Closing since the answer was stated, if this is still an issue feel free to create another help thread on this.
