The auto-buy seems broken.. In fact, the super energize timer also seems stuck at 60 seconds. I' guessing one of the timers is broken. Also, as a suggestion, add an item under the options to "save" game state.. even if the game autosaves often, give players a little peace of mind should they need to reload/refresh.
Update: I seems it's not just the timers, but many things that need to get updated/refreshed--including gave saves. I had progressed to the point of making dysons, but the solar energy was not updating at all. Upon refreshing the game, it went back to a game state from several *hours* ago. At this point, his bug is a game breaker making the game unplayable.
