As Designed Herculean no longer counts towards court physician aptitude

[A Sentient Potato]

Hello there, Potato here!
I was unable to reproduce the issue, both on 1.11.5 and on 1.12.1, From what I can see Court Physicians doesn't increase the Aptitude on either versions, at least when starting a new game. Do you have a save game from 1.11.5 where it did increase their aptitude? And are you sure the game is unmodified?

I'm sad to say that you have been given misleading information. The Herculean trait does not increase the aptitude of court physicians.
Here's a link to the Wiki with more details on what affects aptitude for court positions:
