Role Syncing to Discord

I’ve searched the forums and Google but couldn’t find anything that could help me. I can’t seem to get the role syncing to work with Discord. I’ve followed the steps to set up Nightbot in the channel, made sure it has the right permissions, and added some regulars to see if they would sync to the role I assigned, but it’s been over 12 hours and roles have not synced. Are there any other steps I can try besides removing and reinviting Nightbot (which I’ve already tried)?

Nevermind. After kicking it out for the 5th time it started syncing roles.

It syncs every 15 minutes, but only servers which have been active within that time period.
