Minesweeper program not working, and I'm unsure why

[Elarionus]

I'm trying to make a minesweeper program, but with gophers instead, and I'm struggling to get it to work. It was working before I added the reveal function, and selecting a gopher would make you lose. Now, losing seems to be completely random, and the reveal function that's supposed to show the number of gophers around you just returns random letters and symbols, most often "Q." Can anyone analyze my code and maybe help me figure out where I went wrong? Thanks!

Why did you ignore my answer to your last thread (same question as this) ???

Don't make duplicate threads, especially when you already got replies to the first one.

Oh, I'm sorry! I had completely forgotten I had posted that one on here already. I'll take this one down, thank you guys. :)

EDIT: I can't figure out how to take it down

Delete it, that should be an option available to you.

Better is check-marking the topic as solved.

Look to the left of the page. There should be a box with your user name and a "my topics" link inside.

Click that and you see all the topics you started and/or the topics you made replies to if you didn't start it.
