Our server is using the latest spigot build (updated using buildtools) and the latest spigot-essentials (2.x-snapshot), along with GroupManager for perms.

We were using essentials AntiBuild to prevent placement of certain blocks in the guest world and allow usage of doors and buttons for guests in the builder world.

Since the update to 1.8, essentials antibuild is no longer functioning properly. (I.E: not preventing some blocks in guest world and disallowing usage in builder world).

Attached is a screenshot of the perms we are using in groupmanager, and a screenshot of the disallowing text for using doors/other.

Note: There are no errors or anything that comes up in the console to indicate anything being wrong.
