So I am trying to setup group sync and it seems to not do anything. Everything else with the NamelessAPI plugin is working.
I have given everyone the permission. Everything with group IDs is setup. I am using PermissionsEX for my permissions. Every group has a group permission expect the default group.
Unfortunately there are issues currently with the group sync.
A version 2 plugin is currently in the works which should hopefully resolve any issues, however it will only be available when version 2 of Nameless is released.
