Crates not persisting on official servers?

[MosinFTW 0]

Buried 8 widely-dispersed crates on an offical server about 10 days ago.

Checked a few days ago, all still there.

Today: EVERY crate has vanished! All of them, every single one.

Buried crates are supposed to persist for over a month???

Is there something I don't know about?

apparently there is an exploit for finding buried treasure.  perhaps someone used that and took the crates apart?  I have never buried a crate but I used to bury a lot of bags.  I lost a few of them.

Don't bury your crates. Hide them under a bush as best you can.

Any crate I've buried has been found. The ones I leave above ground don't.
