[2021] Estates and Ancient Weapons.

Hi folks sooo I'm a little stuck on what to do and what not to do. How do we get our estates to make the various parts needed to complete Our Ancient weapons that Only our estates can make. I have conflicting info lol so would appreciate some straight forward less 007 stuff if poss? My estate is Lvl 5 just lol I have lvl 4 mine lvl 3 orchard lvl 4 smithy lvl 3 stable and lvl 2 tailor I think? I am still relatively new so forgive any noob boo boo's, I bought and installed a fishing pond(it used all my mats) but it's still red on my structures even tho it's right there and built. Any help would be appreciated. Cheers Tilly
