On my account when I go to enter member shows, I see all the August 12 shows still listed and need to scroll down to see the current day's member shows. I entered member shows on the 12th and I'm uncertain if they ever ran, but it seems that the game is stuck on that.

Im having this same problem. I had a show scheduled to run the 12, and it still says Open.

The shows from the 12th didn't run. All of the members arena's are currently stuck on 'Open' and can't operate until the bug is fixed.

If you have horses still listed in these shows then you can go to the arena to scratch them, but the shows can not be cancelled.

This should be fixed now, thanks!
