Small Stash destroyable?

Hey all, I’m on a relatively low population server and am making some secret stashes around my house to conceal my goodies that I wouldnt want stolen if people raided. only problem is, the small stashes i had in the rocks disappeared. I went out for a day in rust with my buddy, we made a full loop of the map, and when we came back, the stashes were gone :frowning: are they destroyable, or do they have a time limit or anything?

Any help would be appreciated. !

I believe they degrade if not on a foundation.

3 hits from a pickaxe will destroy them. Placeables despawn faster when not inside structures.
