I cant leave my island to join another island

[renebruin123]

My nickname is rene3141592653 at the JartexNetwork server. Ive played at SkyBlock Fantasy at my own island. I spoke to a friend of me and he wanted to invite me to his island, but he couldnt at first. Then I tried a few things, such as resetting my island with /island reset and I tried to leave my island with /island leave, but it wont let me, because I was the only player of this island. I still would like to leave my island to join my friend's, could somebody please help me? The server is awesome! But still please help me.

If you still have the same problem I suggest you to invite other player/alt account and do /is makeleader (name) then /is leave and you are done!
Hope this will help you.
Have a good day!
