I just figured this out recently. You can log in centrum with meep menu. Here's how
First when you have time, you open the meep menu fast

Then you click on warps.

You click on centrum or any other possible place you can while you're alive.

There's no "This command is not allowed in area" or anything.
I vote meepmenu should be removed. It costed me a god bow once. I tried to move it away from my hotbar while I was holding the god bow, When I clicked on the meep menu while I was in inventory, The meep menu thing showed up, "Warps, balance" I pressed e. The menu closed. My god bow dropped, Someone picked it up and left. He had a long name and I couldn't remember what... Anyways so yeah.
Also a lot of people use this thing. I saw a creeper guy using it. That's how it got me thinking.
Anyways, Hope you can fix it!
