Bukkit

What steps will reproduce the problem?

So basically, i have some Races and Classes that utilizes the permissionTrait, for this example i'm going to take Vampire and Sorcerers.
So Vampire Race got basic perms from the Vampire Plugin from MassiveCraft, while Sorcerers got perms from the MagicSpells plugin. Thing is, once i forced a player into the sorcerer Race and a Initiate class, he got the right perms he was supposed to get and managed to cast spells. Now when i switched him back to Vampire (Where there should be no perms for MagicSpells) He could still cast Spells, (I changed both race and class back to vampire related Race and Class) So i checked Pex and i saw that he had retained all the perms from the Sorcerer race, the ones listed in the PermissionTrait, as well as the perms for the Vampire Plugin, that are listed in the PermissionTrait for the Vampire Race.

What is the expected output? What do you see instead?

I would expect for the perms in each trait for each race to be updated accordingly. In the Vampire Race, you get only the perms listed in the PermissionTrait for that race, switch to a different race? Lose those old perms for the Vampire Race, and update it with the new perms for the new Race and or Class chosen.

What version of RacesAndClasses are you using?

V: V1.1.9

What version of Bukkit / what distribution are you using (Craftbukkit, Spigot, Cauldron, ...)?

Spigot 1.8.8

Do you have an error log of what happened?
