Hi,
just a heads up on the jail plugin.

it seems that if  a player is in the jail OVER a map wipe, the co-ordinates of the old jail are transposed to the new map...
This causes the  player to teliport UNDER the map, if the old jail on the old map was below the level of the new jail on the new map.....
so depending on the settings of the jail....  and the "escape" clause.. it is possible to exploit to gain access to under the map.

So in theory just before a wipe, get thrown in a jail.... & if you are lucky on the new map you will spawn under the map.

Doesnt it save the pos in a data file? if so just wipe it on wipe

Why expect the user to have to manually clean up after plugins ?
this should be handled by the plugin..
the plugin can store the map size & hash in the same file & if they are not the same  as the new map.. trash the file... since the terrain is not gonig to match.

or if its real good move the settings over.
