While scrolling back through the techs I have already researched, I discovered that techs that do not cost any coins/supplies read "0 coins, 0 supplies" instead of just not mentioning them all together. There are too many examples for me to screenshot all of them. These are just a few. (It also happens at the beginning, where the "paid/required resources" are supposed to say "None")
This could just be part of an update, but it seems sort of buggy to me.
