CoordsFinder

Misc > CoordsFinder informs and tracks possible leaking of coordinates through environment.

.coordsfinder lighting - log lightning strikes (default: true) - Notice: spelled "lighting"

.coordsfinder lighting-min-dist - only log lightning if teleported >distance (default: 32) - Notice: spelled "lighting"

.coordsfinder wolf - log wolf teleports (default: true)

.coordsfinder wolf-min-dist - only log wolves if teleported >distance (default: 256)

.coordsfinder player - log player teleports (default: log player teleports)

.coordsfinder player-min-dist - only log players if teleported >distance (default: 256)

All of the defaults are sane, yet in most cases current server software won't send the teleport packet.
