First, IMO the game is great. I enjoy playing several times a week.
But the last update made the game less pleasant to play.

Fights accessibility, once fluid, feels clunky now. Fights are laggy. I sometime have to double/triple click to target or move.
Elements of the UI like the white spots showing movement posibilities or the range indicator sometimes appears then disappear for a second when i select an unit.

One minor last thing : Cities are no longer part of the fights. That's a good thing. BUT once the fight is over city hexes sometimes don't reappear. I can see the bonus on the tilles but the buildings are not there.
