how close can 2 players live next to one and the other i havnt played much this week but i come back to play and a other player moved or setup base under 10 blocks above my base is that okay or ?
Usually, if your base is claimed they will get a warning in chat that they are building too close to a claim. If I read this correctly they have build above your base. If you had your base there first and you would like them to move you could create a ticket by typing (/ticket create) ingame and filling out a description of your problem then staff can look into it further. Make sure to try and be in the area of your base when you create the ticket. However I do not recommend moving there items without permission. I hope this helps
like i didnt claim the hole place because i could bot but still i started a little on a dome and if i dig to the top of that dome i dig into the other players floor and the dome is 10 blocks max or less
Well. As I understand you built underground (correct me if im wrong). A rule on our network is you need to have a visible sign that you are living underground. Again, if you would like to make a ticket we could look into this further.
