60's league games didn't run last night

The 60's league I'm in didn't run games last night although the 70's league I'm in did...???

One of my 60s leagues ran but the other one didn't. My 70s league also did not run.

I see there's a similar post in the ATG chat, so I think it may have been a general glitch and not just related to the Mystery cards.

I also had an 80s league that did not run last night.
