Hello,
Whilst I’ve been playing with the in-house production of almost everything, I noticed that when I got the “Make Aircon” - I can’t actually fit it, because it’s not being used.
“Fit Aircon” Only requires “Climate Control Unit”
So I believe the “Make Aircon” needs a “Make Climate Control Unit” upgrade, to fit in with this, otherwise “Make Aircon” is defunct as soon as you research and apply Climate Control?
