Hmmm.... now we have tables disappearing from the lobby - not good.
This morning, there were very few $100NL 6-max tables showing up. I thought it could be just because it was in the morning, but when I checked a while later, there were
NO $100NL 6-max tables showing up - including the one I was currently sitting at

(and I tried toggling the "Hide full tables" button to no avail)
Now, I left the client running when I went to get some lunch - maybe 45 minutes or so. Here's what the lobby looked like when I got back -
And this is what it showed after I closed the client and immediately reopened it -
As you can see, there are several more tables visible after I restarted the client (5 vs. 13)...
