Moved over from General -    I found three sleepers and a large number of foundations/chests/cabinents/benches etc inside a formation on an Oxide server I have. obviously they don't have any permissions to noclip etc. Is this another known exploit. I am using NTeleporations etc so I wonder if they were able to place the foundation inside the rock then set a home - TP to the home and build from there ?

I still cannot figure out how they placed the entire foundation inside the the rock.  The only thing I can come up with is to place the edge of one foundation slightly inside the rock,  then build another next to it.  set your home.   You partially spawn inside the rock and can removed the old foundation (If the server has the Remover Tool) and reset your Home inside the rock now and come and go as needed. 

Thoughts on this ??

You may be right and I appreciate what you're trying to do but, please, reproduce this suspected glitch and until then let's not speculate.  Developers cannot reliably fix something like this without being able to see it reproduced or reproducing it themselves.

Seems like a terrain bug with parts of certain maps.  The plugin already blocks building in terrain or through rock.  If you would care to show me, send me a message or find me on Steam, etc.
