follow_polygon_edges crashes

[shaybarak]

There is a bug that causes an access violation in follow_polygon_edges. It's most likely in the loop that begins at ShortestPathInPolygon.h:238, though I'm not sure because the stack trace in Release is not accurate. The bug could be either in the loop's body or in the exit condition.

This crashes the player and causes us to lose the match.

To recreate the crash:
Run the simplest scenario, under Input. It's the standard maze with both players and all three targets outside the maze.
Player B crashes.

Please:

1. Test your code against more than one scenario!
2. Either fix this by the end of the day or revert back to Oren's code.
