Basically what happens is that when I do /home I go back to an island I used to be a coop in. The reason for this is because I decided to kick 2 people out of my coop because I haven't seen them for months. It said something like the coop was deleted but I didn't really think much about it then. A day later (today) I was trading with someone and they were at my island. At one point while he was looking around I did /home and expected to land in my pool of water, but landed at my old coop. I did a tp to the person at my island. I did coop leave cause I realised I was now in a coop with my old coop but I forgot that I lost my stuff. So I lost my inventory. I don't really care about my inventory but can anything be done to allow me to set my home back to my island. No one else is in a coop in it, it's a solo island and I have spent so many hours on it. Please. I'm so desperate to have my /home to be set back on my island.
Well I made a post regarding this Co-op Glitch below: Issue: There is a bug which probably is not new and I think it affects many co-op players. I realized that if you join a co-op island and decide to /coop leave or if you get kicked, even after you return to your new or replaced island this glitch will still take you back to the co-op island when using /home. What Its Problematic: The problem is 2 fold, the first being that you simply can not start your own island as /home always takes you back. And secondly this glitch is worrisome because you may kick and unwanted player and yet that player (who may be upset with you) still has the ability to do /home and grief or steal ect. All without you know they have the glitch. FIX: I did find a fix. Having them kick you or you leaving does not work. Even though you can do /coop and see your not part of the island the glitch still assumes they are part of the party, and any attempt to anything co-op related yields the message "you are not the party leader". The way to fix this is have the party leader disband the group by leaving it. So if you have players A,B,C,D and you dont want player D. Just disband the group and re-invite player A,B,C.
I dont know if this exactly pertains to you, but in order for you not to end up at the other persons island they (the coop owner) have to leave the original coop, Im not sure if this resets their island, its just the only fix i know of. The only other option is to use /homes and set your home at your island.
