Hi, today Ive found this bug - i wanted to build study, but had only 20 gildens (study requires 25). So ive decided to trade some of my materials with one of neutral races. Ive traded 25 materials for 25 gildens so i've had all resources that study needs but still wasnt able to build it - so game didnt checked resources counts after the trade. This check was performed after i clicked end turn button, but i suppose this is not exactly how the things should work.
