This has been fixed in 0.5.1 which is currently uploading! I figured out what it was, it was actually the fact that it wasn't adding to the exit counter, which is used to determine which exit will be the actual exit. The reason that it wouldn't add to the exit counter is because of the fact that I was an idiot and made the exit trigger set itself to be inactive before the exit counter would go up, causing the script to stop working once that happened. Now, the exit counter will go up BEFORE the trigger sets itself to be inactive, so this shouldn't happen again.
