In the course of building my spreadsheet, I have come across a few anomalies that I'm hoping someone can explain. I played Fish Tycoon extensively, so I was not surprised to find a "flowerless" flower type. However, sometimes a combination of two flower types that has produced a fairly constant result will return a flowerless plant. Now I am second-guessing the combinations that resulted in flowerless plants earlier in the game and wondering if that just happens from time to time, but is not a constant. Any thoughts?
