Zhu Xi's Legacy - Yuan Dynasty + Siege Workshop + Ram - 10% discount to all units (Yuan Dynasty bonus) does not apply to Rams from Siege Workshop

Age of Empires IV IV - Report a Bug
1

For Zhu Xi’s Legacy, getting both Age III landmarks gives you Yuan Dynasty, which reduces the cost of all units by 10%.

This is not working for Ram built from the Siege Workshop.

A patch changed the Ram to cost 200 wood, but it still costs 200 wood (instead of 180 wood) with Yuan Dynasty.
