Well, My partner stopped playing for a while (more tham 6 months) and I want to put people on the coop, but he is the Island owner, is there anyway to transfer the island ownership/host?

 

Sadly No, the plugin is designed is there is only one owner. I suggest starting a new island.

 

There is no way to do this sadly.

 

Sorry, we cannot transfer owners of islands. I suggest letting a very trustworthy friend help you move your things to another island(whilst being legal to do)and start a newisland.
