Time running after I made a move - Network issue?

I'm very sure it's NOT a network issue, because this has happened to me, when I have plenty of time on the clock, and after this happens, I am always able to start a new game immediately with the same opponent, whether I had a lot of time or not.

Also, I have absolutely no issues going to any other website. So it's almost certainly a bug that should be fixed.

Just replying here to state that this is definitely not fixed. Still keeps happening frequently...
