Unable to access a particular game

There seems to be an issue with game# 4424143, Game of Seth_emory1999, Europe 1914. I can get into every other game I am playing but this one. I WAS in, then it seemed to dump out and I can no longer get in. Any ideas as to what that is?

I can access it now, but it is still strange that it happened. Would still love to know why that would happen.
