So i changed a couple of commands and deleted a few timers weeks ago, but Nightbot still posts the old timers AND does show the commands in their old version when they are posted in chat.
Is there any method besides join/part channel log in/log out to force a refresh of all commands timers?
It is actually not possible that it is persisting/posting deleted commands or timers. Once those are deleted, they are deleted from storage and are no longer retrievable. You may need to double check your configuration on other commands and timers.
