rocks not respawning

I have a rust server and I noticed that rocks don’t respawn and I have to go further and further to get stone
any one knows what’s going on

Not the case on any of the servers I play on. Rocks don’t necessarily respawn in the same place though, so if you are farming the rocks near your base, they are respawning elsewhere, but if people aren’t also farming those rocks elsewhere they will remain there, and not respawn near your base again. Basically, if people are farming rocks all over the map, they will respawn all over the map, but if you are only farming from one area, eventually there will be no rocks left because they will have all respawned elsewhere.

ok thanks
