Some permissions are failing to function as intended under sub-channels that they are applied to. They work in root channel though.
For example the permission Enter is set to deny for @all under a Sub Channel of Root. Everybody is still able to enter that channel regardless.
Yet if the same channel has Traverse set to deny, nobody can access it. However this doesn't help when you want players to enter the sub channel.
This is a very problematic bug, please fix this for the next update.
