Player not beyond world edge but server thinks they are

[taikedz]

Hi

I was asked to look into a "spooky" happening just now --

A player "Libby" was adding iron to a furnace when, they say, they were inexplicably teleported to spawn - no teleport potions, no admins or moderators online, no command typed. As a result general speculation amongst players about there being a hacker amongst them spread and "Libby" decided they would not play on the server anymore out of fear...

Turns out the more accurate description is:

* Libby was mining
* Libby disconnected for a few minutes
* when Libby came back, server thought the player was out of bounds, so moved them back to spawn on logging back in

2016-11-03 18:53:16: ACTION[Server]: Libby leaves game. List of players: <PLAYER LIST>

...

2016-11-03 18:53:24: ACTION[Server]: Respawn position for player "Libby" outside limits, resetting
2016-11-03 18:53:24: ACTION[Server]: Libby [74.210.226.30] joins game.
2016-11-03 18:53:24: ACTION[Server]: Libby joins game. List of players: <PLAYER LIST>


Is there any reason why the engine would think a player is outside of limits when they clearly are far from any edge....?

IF this was on a public server and IF this server has a certain mod and IF this player was outside that mods specified range, the mod would "think" to itself: "Oh. That person is out of the boundary specified. Must teleport them to spawn." On an old server known as Craig's Server, this mod exists. If you go outside of the just-a-little-bit-less-than-32000-blocks-limit, you are teleported back to spawn. Mind you this is ONLY if this server has that mod.
