Weirdly essentials.* and every other permission wildcard currently does not work and shows the no permission error.
I have Moderators with basically just *, they can't use any Essentials commands for instance.
I checked the plugin.yml, however it is not modified, so the issue lies somewhere in the source.
It works with spigots essentials. It's probably this commit ac0858d

I'm using the latest 1.8.3 build, the latest GroupManager and the latest EssentialsX build.

Yeah, looks like VaultHandler should inherit hasPermission from SuperpermsHandler.

Nice, thank you.
You should get permission to merge imo :D
