Ive created a Npc for Each class (role) on the server. So if a player wants to change Role at anytime they can, by doing a small quest.

The Reward Command is set as e.g "pexrank Mystic"
It worked the first time but after when reloading (questadmin reload) the command changes to "pexrank Mystic" (no ) and the reward is no longer given.

can I get some help . Ive been losing it over this one.
Also when going back to Edit some Class/group/role in edit quest. I literally get disconnected from the server.

Sounds like you're trying to give the Mystic rank to someone who's already a Mystic. That would not be a Quests issue. If I am misunderstanding and this is still a problem, please create a new Issue.
