Hi, The info in Building Tech ...enables new types of buildings, as well as increase the rate of all construction...some types of buildings will not be enabled until other tech improvemnts has been made - if the answer is a spolier please (PM) me.
Also, I am on my last puzzle, thank you madam, does the game continue and your builders actual start building new types of buildings and the tropical huts disappear? or is that line from the Village Tech Building info just 'flowery' writing? patiently awaiting a response. Thanks.
