I went afk on my island, came back a little while later and i was dead... no big deal until i tried to /is home and i didn't have an island... i thought it was just a glitch so i ended up creating another island through the /is menu and it made a new island... then i noticed my death spot was still on journey map so i flew there and my old island was still there... but only a single chunk of it.

I am sorry for taking so long to look into this. Creating a new island will delete your old island. If something like this happens again, please let us know. I was able to find your base via a backup from earlier on the 18th and used that to restore your base to the new island you created. There may be some progress lost due to it being a from a backup. I adjusted your spawn and you should be good to go. Please let me know if there are any problems.
