Modders please help to create scurvy mod [Civ 5 BNW]

[Maximum]

Hi, if you still remember there was such a New World scenario. And in it, the ships received a "promotion" - called scurvy. Is it possible to add this "promotion" to a single player game? Thank you in advance

 

[Maximum]

And in order not to create additional buildings, it is possible for this promotion to be used when studying navigation or building a seaport

 

[Nomad or What]

It should be fairly easy to do since it already existed in a scenario. There is mention of it and some of the extracted code in another thread:

I'm not much into creating mods nowadays, but hopefully this helps.
