Configuration :

Players.Rollback

This setting makes the whole level reseted at game end. This means that all block placed/broken will be reverted to their original state. To detect what is a level or not the plugin catch where players goes and save chunk arounds. Only players playing Tribu are considered. This means 2 things : every player not playing Tribu can break a part of the level if this part was not visited by a Tribu player, if a non-Tribu player want to build something next to a level, this will be reverted. This feature can makes your server lag a bit but should not freeze your server unless you have a really low-resource server.

Players.AllowBreak and Players.AllowPlace

These 2 settings allow or deny players to place or break blocks. The permission "tribu.super.place" and "tribu.super.break" overwrite these 2 settings. If a player try to place a block with "AllowPlace: false" this will be cancelled but if he has "tribu.super.place" this will works

Level.Jail and Level.JailRadius

The jail prevent players to leave the death spawn after being killed. You can choose a radius around the death spawn where they can go.

Level.ClearZone

The clear zone is a radius from initial spawn. It's mainly used to determine if a mob is inside a level or not, then if it's not a Tribu zombie he is removed. This setting is useless if you have set either WorldExclusive or ServerExclusive to true
