Development version 0.9 latest (the latest update fixed game stuck on loading screen of scenarios manned missions).
now the manned missions-Cydonia Mensae loads and starts BUT. when pressing Esc and then return to game. the game freezes as soon as you return to mission.
tried two times, same result, waited several minutes, nothing happens.
run game, start scenario manned missions-Cydonia Mensae , press Esc for game menu> press Esc again or press Return to game. freezes after menu disappear and the game comes on.
today reinstalled all windows visual redistributable packages from 2005 to 2013 x86 and x64 sp1 and security updates. (to see if its helps the loading stuck problem).
