Greatly enjoying the game!
Ran into a bug where Buckets Wheel and Water Wheel are in my deck but, for the purposes of starting Water-Work, they don't register so I can't start Water-Work.
That's not a bug, just an unfortunate oversight by the dev - there are 2 Water Wheel cards and 2 Bucket Wheel cards - one blue and one red of each. They have the exact same names, but the waterworks construction only takes the blue ones, and the red ones have to be built like a construction to get the corresponding blue card.
