According to the Patch on Feb 13: Age of Empires IV – Patch 12.2.3327 - Age of Empires - World’s Edge Studio
Ottoman “Military and Technology Building discount 33% → 40%.”
Siege Workshop base cost 250w times 0.66 = 166w, the current live version cost of Ottoman Siege Workshop, uses the 33% discount instead of 40% discount
250w times 0.6 = 150w, the correct cost, when using 40% discount.
Please adjust the cost of Ottoman Siege Worshops to 150w, thank you.
