I made conways game of life and as far as I can tell everything in the code looks right... until I run it. It doesn't behave like it should despite using conways rules. There's explosive growth, weird tunneling and other behaviors not seen in proper implementations of cgol. Anyone with a second wanna tell me what the heck I did wrong?
