This is a huge head scratcher (at least, it has been for me). I literally have only one problematic line of code I've written, that checks out in Visual Studio, but starting my game immediately boots me out with a null reference exception error based on that single line no matter how I jiggle it around or configure it or rephrase it. I have a lot of experience with collections of objects in VB, and as far as I can tell, I'm not doing anything wrong, but I've never used collections of objects in C#, so.
Here is my code.
Now, another thing to note, before someone brings it up: I do have a Seed class, so I'm not trying to declare a type that doesn't exist. :) You may also ignore my Update, and Water/Cash/Toolmode variables. I just included everything for posterity.
Any time I try to do ANTHING with my SeedBox (which is declared as a list of Seeds, or it logically seems that way to me), it gives me null reference exceptions up the wazoo. I've tried all sorts of alternate codes in place of
Maybe I'm just not understanding how lists work in C#. Anyone have a good answer for this one?

On a completely different note; you probably shouldn't call GameObject.Find every update. You can store the references during start instead:
