Ardashir I: progenitor of the Sasanian dynasty, reinvigorated the idea of a Persian empire as a successor of Achaemenid Persia. May have an aura or tech about adding vigor to the civ, for example increases building construction speed Shapur I: tolerance for religions other than the prevailing Zoroastrianism such as Manichaeism or Judaism may present an interesting opportunity. Especially Manichaeism as a potential world religion in a what-if scenario perhaps? May give increased influence over the map such as increased territory bonus. Maybe also enable some Armenian unit via his conquest of Armenia and governorship of his son and successor. Shapur II: counter to Shapur I, something about religious doctrine, such as stronger priests or temples? Also enabling war elephants. Khosrow I: tax reform giving increased resources per resource obtained from sources, and bonuses to noble Aswaran cavalry Khosrow II: not sure, he appears to be partly responsible to bring the empire down? Why not something to represent quick expansion and loss, such as globally reducing building capture, or to make it a bonus, reduce own building capture and while reducing capturing enemy building even more.  

Bildschirmaufnahme 2026-06-05 113133.mp4 I could add a person (or a donkey?) pushing the grindstone in a circle? Or maybe that's too much (performance wise and visually)?   I can take a look into it. The han forge has something similar where we can get some inspiration.

Okay, but what changes in DE would make that happen? I'm at a loss. 

Nice. Which part are you animating? The grindstone? I wonder of you'd be willing to help animate the Sasanian farmstead. It has two sail-driven grindstones. Perhaps as with the forge smoke, the sails can turn when the farmstead is researching (rule of cool). 

I fixed a few refs in research manager and had a match vs AI where their units didn't go idle. I'll attempt some more test matches tonight.    EDIT: Nevermind. Still happening:   I see they have plenty of food, but have stopped gathering the wood needed for phase-up for some reason.
