I think I have a huge problem. I have seven Array objects with about 30 instance variables each to save in local storage lol... It's crazy that I've only just realized this problem that breaks everything. Anyway, thanks.
This looks pretty good for the array structure.
The rows can be map numbers, and the columns can correspond to one of seven objects. Then it will be convenient to refer to them and store them.
It will also be convenient to fill in the initial data via the file.
But you will need to spend time changing this.
