Several people reported to me over the past few days that the cards were disappearing for players, so they couldn't play their hand, and the computer played for them. Frustrating!
I was only able to reproduce this problem when the browser had been refreshed. When I did that, it happened a lot!
Once I could reproduce it, it wasn't too difficult to figure out the problem, and apply a fix to the site. That happened this morning (around 6:45 EDT), which is why the server went down for a brief period.
Let's hope this bug is gone for good!
