I am big on earning achievements ... I checked the list of achievements that are implemented and one that is listed is Investments, which is under Wealth -> Infrastructure.
When I looked for its components, such as A Great Feast (food storage achievement), Wooden Crown (wood storage achievement), and Mountain King (stone storage achievement) they are not listed and not implemented. And of course, when I satisfy the requirements, they are not awarded. This probably has not come to the attention of too many people since most of us are in a rush to move out of Stone Age and enjoy the higher learning benefits.
My question is, how can achievement "Investments" be implemented and considered "working" when its components are not? So although it isn't a high priority item at this time, the rationale eludes me. Since I am spending more time in Stone Age, (and you are encouraging this) I would like to be able to obtain all possible achievements while I am there.
