2003 S3 is currently broken

[SubwayMan]

2003 S3 is not currently working. Instead of fixing this, I'm creating an issue because I'm too lazy. The issue is an indexerror when attempting to get adjacent cells. In my original code, I used a try/except block to catch these, however I tried adjusting the code to not use them as exception handling comes with large overhead. (The original solution still passed, so I could've left it in. Oh well)
