When you have Golden Cuirass for OOTD Men at Arms, if you upgrade to Veteran or Elite, all MaA currently on the map lose their Golden Cuirass and only NEWLY PRODUCED MaA receive the buff again. I also tested against a boar of a MaA that was already produced and upgraded to Veteran and he took full damage all the way to 0 HP.
The newly produced MaA after upgrading to Veteran or Elite took reduced damage from the boar after 20% hp as expected. This means it is not just a visual bug.
To reproduce, create Man at Arms with Golden Cuirass in Feudal or Castle and ensure it has Golden Cuirass buff on its display card. Upgrade the unit to Veteran or Elite and the buff for already created MaA disappears and is verified by letting a boar kill it.
I just tested with Crossbows and Bodkin bolts as well and it behaves the same way. Have a crossbow out on the map, upgrade Bodkin bolts and it gets +10 Siege damage, upgrade crossbows to Elite and the +10 Siege goes away.
Just tested knight charge as well after recommendation Trained Castle Knight, upgraded warhorse charge for -25%, upgrade knight to Elite, -25% buff goes away. New knight produced after upgrading to Elite have the buff again…
Explains a lot about why my MAA don’t feel as strong going into castle after building up a force. This, along with eco numbers for the villagers really hurt OOTD, I hope this gets fixed soon!
Just an update - still an issue even after the most recent patch.
Separately Also the golden cuirass buff on the unit placard still displays 20%/20% instead of 30%/20% however that portion is just a visual bug as tested against a boar it correctly activates at 30%.
