Ok I read the production rules,but Im just not getting it.Hw do I assign the npc to production.And if I pull up the que and it says 12 workers working and 0 on idle does that mean they are working already.Also if the item says 8-10 workers can i put more on it and if i did would it make a difference.
Assigning, I believe they have to be assigned/owned by the production faction and in the entity you are producing with (ie factory or shipyard). It should pick them up automatically.
If it says they are working, thye probably are so long as you are looking at the top on one the queue list.
You cannot add more NPCs (as far as I am aware) once you have started production. And yes, adding more NPCs can make a difference. There is a perfect number of NPCs to use for production of the various entities, and if you use less or more, then the time to produce will get longer.
