Playing the 18th January version with 24th January zip update, I've finally advanced the "Ardent" storyline to where you get a (very small) ship and put to sea. Direct-sailing from Havana to Santiago takes several days and in previous versions would have earned me a good bit of experience, specifically in "Navigation". In this version I got a grand total of 0. Also, failing to open chests used to earn me a bit of "Luck", now it doesn't.
This is at "Sea Dog" level.
