Hi,

I'm getting this error:
(EDIT: Different error from title, first one was resolved)

Failed to run a 2.00 timer in 'DiscordRoles v2.0.1' (NullReferenceException: Object reference not set to an instance of an object)

DiscordRoles now requires Role ID. Role Name will no longer work.

Second error was resolved. Looks like DiscordRoles doesn't want an update rate of two seconds. Set it to ten and it worked.

Two Seconds should be fine. That's only there to avoid being rate limited by Discord. What issues were you having with two seconds?
