I usually in the defensive state during the first 15 - 20 minutes, I waited until I've researched level 2 armor and weapon and build 60+ army before I push out.
While the freeze seems to happen if the player immediately leave the main base and attack / destroy army producing building before the 8 minutes mark [A.I start building army to attack your base]. It is very difficult, and require a lot of multitasking like you said but it is possible.
It messed up the validator and triggering since the building already been destroyed but the 8 minutes mark command the destroyed building to produce units.
I've tried few adjustment and will be sending the new version to your email.
Thank you for the report TChosenOne.
Yeah I generally send Sin Ar to attack the top left base, because I don't like to fight that sudden reaver/immortal combo.
Very sorry to keep being the bearer of bad news, but I got another freeze with the newest verision.
Also there's something I don't understand. When Sin Ar says that she'll tell Stukov "something" (or something similar, I can't remember exactly) there's no additional lines, that really breaks the flow of the story.
Something that would be nice in Red Snow is to be able to sacrifice time for energy. I spent a lot of time waiting around for my energy to get back up, yet finished the mission with >30 minutes left. A slightly inefficent time->energy ability would increase the speed of people completing the mission, and get people a little closer to the limit.
Of course it can only be used while out of combat, all enemies heal to full, etc etc.
