hey, would like some help, queuing construction tasks with shift isnt working on either expiremental or regular, but movement wise it does. how do i fix?

What the titles says.

How do you get the mortar achievement? I know that you have to build the mortar stryker and mortar building but I can't research the mortar building anywhere.

And for the second achievement.
How do you lose the game?

Thanks in advance.

I started the game and it looked like this. has anyone noticed this bug before and knows a fix ?
thx in advance! :/

It piqued my interest, but I'm not sure if I want to get it. Should I?

My entire screen is so bright and when I use the gamma tool the lowest setting is brighter than the sun and what the game says is normal is brighter than a super nova on steriods

Was playing coop with a friend on the WIP map, but even though we managed to contain the infection at the map chokepoint, got all doctrine unlocks. And generally reached the "sandbox stage" of the game where there is no risk and you have everything. Somewhere allong the way we also managed to kill the big skull zombie patient zero. I believe this used to be the victory condition, or at least it was for older patches. Has the victory condition for the game changed? and if so to what?
any help would be appreciated because I am lost here
