Rogue Units or Frozen Units

So, here's a new one.

Playing an Event game and have an army of 50 inf and 2 HT's stuck . Can't move them, can't split them and if you try and drag them you get a "Server state different than Client state." BTW, has been going on for over 3 hours now. Here's a couple of screenshots to show what I'm talking about.

Oh, I have reported it and expect it to be resolved but it is annoying. Takes a whole army out of play for awhile.
