Blocks mysteriously disappeared?

[Neotrinity7]

I just logged onto my personal server used with some friends, and every single wood-based block just vanished (or rather, every single one in my base chunk?).
So that includes:
All the wooden walls and floors
Chests
Fences
Pressure Plates
Beds
Wheat for some reason?
Somehow doors and trap doors aren't gone as if they're teasing me.
Whether they were planks, logs, stripped logs, they were all gone.
I spent so much effort on this base because it's my first real server and this really really saddens me to see all my hard work go away.
Is it possible to troubleshoot and maybe pull up an older save for the server? I know I'm only a free user, but I hope I can get any help I can.

Thank you.

This seems more like a grief.

Wheat isn't exactly related to wood, and trapdoors are not really something you would want to break during a grief.

When you leave your MH server with 0 players, there is still a 10 minute uptime, in which a player could join and grief. Sorry about that!

Also staff are not able to rollback servers, big oof but worth knowing for future occasions. Better to just make backups of your world on your pc.
