Game keeps cancelling my production que

As the title states I cant produce a single unit with this problem economy is good and enough space as well.

Have you ever been able to play properly? How do you try build? Economy is good as in you just have your commanders income?

do you keep pressing s when your engineers are selected?

I know your problem.

Dont use WASD to move the camera.

Out of curiosity, did this happen in a team game? Any chance your ally cancelled your production queue?

Also, when adding new orders to a fabrication unit's queue, remember to hold the shift key or it will erase all previous orders.
