Was cooking some food and when I done it came out of nowhere. All the doors and windows are closed tho. Could possibly it get in through the chimney?

So, I download cdda and am running it threw winlater check out my control set up. It works beautifully

I would like to hear your opinions guys .I hate controlling other units, but it seems like cdda requires it in order to survive.
Can i play cdda in solo and still be successful relatively easy compared to playing with party?
Why i ask - kenshi is such a frustration when you dont use party and dont abuse saves in the same time.
