My server has been half deleted

[SquidInATux]

This is my first ever post on here but my friend logged onto my server and was at world spawn, came back home, and found his entire base thanos snapped,  mine was still there but a recent addition that was deleted, along with my nether seed which is completely different and a shack i built also vanished too. An item i crafted most recent right before this all happened is still there though. None of the deletes match up in order sense both bases were built at same time but only one is fully gone, ( with some parts gone from mine). im very new to this forum but tag or whatever me if you can help what so ever.

Try checking /worlds to see if you were moved to a different world, or use a backup, if neither of those work create a support ticket here https://minehut.com/support/form
