There was a problem on the server when you logged in that was causing plugin commands not to work. Not sure what it was, but restarting fixed it. I have /crush enabled for players, but it only destroys structure parts, but unlike /destroy it will destroy it whether or not it has another part above it. So you can make castles in the sky and stuff.
I don't currently have DestroyMode installed, but that will destroy deployables.
The server is used for testing, yes, but I also would like players to live on it. I login at least once a day to make sure things are still running OK, and spend several hours a week logged in trying new stuff. I was contacted by a player who was looking for a new home for his clan, and they all came the weekend before last and played for hours and built most of the structures. I wiped it so they could have a fresh start. But they couldn't get any of their rival clans to come. So they haven't been back. And I've not seen the ones who friended me playing Rust much or at all since. So they may not have been all that into it.
I really dig Legacy, and am not as enthusiastic about new Rust just yet. If you have friends who are looking for a server to call home, and rivals who want to play too, I would welcome you all with open arms. You want airdrops when you login, you got 'em. No military gear, no problem. I'll setup the server to your taste.
I have some really cool shit to finish after I get Rust++ repaired. I'm going to need players to test it. How do you feel about getting a Steam message, or an email, or a txt message, when your house is attacked? What if you could setup your house so that it could defend itself for a while until you can login with your friends?
