All information in here is also at spawn on the server. What you (yes, you.) are about to read has been documented in game.
So on Sunday night, I noticed something during an RP, things were going normal, nobody was griefing etc.
I attempted to warp to Big Nose Falls, but it gave a err.invalid.warp message to me.
Attempting other warps gave me the same result: nothing.
I did the command to list every warp, and it showed the same error message. There was an error, because there were no warps to show.
Now, I don't know if we reached a critical mass of warps (there were only about <80) but all the warps suddenly disappearing without warning counts as a bug to me.
If you look now, there a few warps, I set them for important places.
Something else interesting of note: The warp naming system only supports alphanumeric characters now.
