I also started over. I did everything as indicated. But the copper cable is 1/10 again, the technology has been studied, but the mission is not completed.
One more point - I use Linux Debian to play
At the same time, there were -17 trees in the warehouse (a negative amount after studying the technology that requires wood twice).
Maybe this is related to
Bug:
Quest First electronics
22 Cooper cables in Storage
Wooden circuit discovered
I only use Linux
Try again. The situation has not changed
How play this on 2560x1080??
Not started playing on Linux Debian
