I will add links to each map and the particular zones on a later date. Also, I will make personal pointers as to what significant landmarks each region has. Also, I will add brackets on the sides of each zone so you can copy-paste the checklist and mark which zones you'd found at least one glitch in. After finding a glitch in each zone, you would wipe the board and repeat the process. Let there be exploration!
