Hi, i want to know how should i config an auto command.
I want to execute the following command every played hour
Command: token add {player} 2
I typed in rewards, and in game i find it defined
when i type /ontime rewards add command token add {player} 2, it says that is not defined

If you are still interested in an answer to this question, please post a link to a copy of your rewards.yml file that includes the definition of the above command reward.
