Bugged daily?

I just went to start the daily, but everything's greyed out, except for the Leaderboards. I can't even do a practice run.

I thought it might be that I didn't have the latest update, but there's nothing queued, and the latest thing I downloaded was about 8 hours ago, so I figure it must be up-to-date.

I couldn't see any other topic on it. Is it just me?

e: Restarting Steam didn't work ('Not responding' during startup), nor did rebooting. Poo.

e2: Derpity-doo. You can't do the daily with a mod running. I had the tinted rocks one on. Leaving this up for anyone else who needs the reminder.
