jump off a counter and die

This server has a strange death add-on.
Ask people a bunch of nooby questions (this was true)
There's nobody around.
Try to find a way outside
After looking around again, you see some signs:

You follow them.

However, the game freezes. You're confused, is this game just unstable or what?
It carries on going, but is very laggy. You try to go over every way you think you could speed things up, and eventually end up in the game's console.

That doesn't look good. Was this happening the entire time or did this just start happening now?
'Ow!'

your blockhead screams. You died, but for what reason?
You respawn. You stare. Freeze. Crash.

You continue staring at the screen for what seems to be years. Snapping out of it, you turn blockland back on, and rejoin that server.

Everything's okay. Did you imagine that? Did anything actually happen? Everything seems to be exactly the game, even your player's back to normal.
What now?
