I am making a plants vs zombies project for my class, and I don't know what I changed in my code, but I can no longer place either my Sunflowers or my Wallnuts. I will paste the code for the world, abstract plant class, wallnut, and sunflower below:

The error is that I can no longer place Wallnuts or Sunflowers, if anyone could figure out why, I appreciate the help.
