It's gotten me a half dozen times over the past two weeks in several games. I've had turns not register when submitted with 0:30 on the clock all the way up to over a minute remaining and in all cases I received the green dot only to be shocked beyond belief when nothing moved during the playback. Argh!

Of course the simple solution is don't get caught with your pants down and a short clock... if at all possible.

I've noticed in my games that the map often freezes, stopping the clock for bit. So just be aware and get those moves in earlier.

Yikes, typo city (on my part).  Anyway, Mc, remember that infamous FFA game (or non-FFA game, as the case/opinion/definition may be) when I missed my turn?  If I recall correctly, I submitted with a minute or so remaining and it reset without getting my turn in there.  I figured it was because of all the units, which seems to overload the game or certain players' computers/connections at times, but it may have also been this same clock issue.  And also, now that I think of it, I may have actually clicked submit in that missed turn with oVo, too, when it switched without submitting my turn.
