A warning message pops up that the site is unable the fetch the game (db error). When I click on Play Game nothing happens and it reads Fetching...

The game just advanced, but without allowing anyone to input a turn. It now appears to be working fine, but something happened. I usually try to look for clues as to what the cause could be, but in this case I'm stumped

The machine that holds the game history database failed for a period of time.
The good news is the that the new BATTLE FORCES system compensated for the outage and continued on, the unfortunate result is that players would not be able to access the given turn that was generated during the outage for the specific game.
Low priority, but we can make further improvements for fault tolerance, time allowing.
Thank you for reporting, it was a tricky one.
