Hi,
Experienced it twice at different times and stages of the battle.
At some point my mouse stops being usable in game - I can move around the map using wasd or arrows keys, but I can't click on any unit and with this inablility to control the unit I can't play.
Game continues to run, but I can access no game menu button with the mouse or even using the Esc button, so I can't even report the bug from ingame.
Was forced each time to Alt+F4 the game.
P.S. couldn't upload the output_log file - to big - 9796KB, email sent with the file.
