I was wondering with the wagon workshop or other workshops in general is there a way to tell my workers to just to build with out having to move the materials from the warehouse to the workshop? Or is it having to return to the workshop every so oftern and tell the workers to move more materials over to make the item? 

usually once you set your workers a task they will continue the task until their stamina depletes or they run out of materials. Everything isndine automatically 

I suggest just saying town storage rather than warehouse or workshop for less confusion.

You'll never actually see workshop anyway unless you walk around to the highlighted door that won't open.

Next info I wanna share is you can use a couple towns and a set of workers belonging to more than one town as long as you have some of same materials in each town.

Ship building is more complicated. For that you can have 5 workers each working on a separate part or maybe 5 workers on 1 part . That's because the quantity for each part can go into the hundreds of thousands. Even changing the amount each each worker can do each part will still take weeks to complete a frigate or Sailboat manually.

That's the reason many choose another way to get those boats. GL if you do it. I have done it more than one way but manually is pretty exhaust ing.
