The server's back up, luckily the SDCard was still readable on a computer.
I'm now wondering what caused it. It crashed when I joined the server.
The server is down again.
Whachyou looking at me for, I didn't do nothing! ...
I need to recompile a newer version, someone hit the bug I fixed some time ago - a new world was started mid-play and it too long to initialize, so the server assumed deadlock and committed suicide.
The server's back up, Nether portals have been disabled.
I just created an account to let you know that it was me. I was looking around at the different designs and I slipped into a nether portal on one of the designs. Sorry.
No worries.

You had no way of knowing it would crash.
I invited some of my friends over to

They are building right now

One of my friends found a concerning bug. Apparently if he spams hard enough he is able to place blocks outside his plot. They aren't client-side, because if he relogs he still has the blocks.
