A base with 2 workshops and 20 workers produces things at 4x the speed as a base with 1 workshop and 10 workers. I can't be sure that's a bug, but it doesn't make sense to me that it would be that way. (Example: plasma grenades take 72h to produce at a base with 1 workshop and 10 workers, and 18h to produce at a base with 2 workshops and 20 workers)
