Fixed Stuck Bot Issue:

Back stairwell in the Axis hangar - added extra pathnodes on the stairs and under the stairs to help prevent bots from falling off, and help them re-orient to escape if they manage to fall anyway.

Note:
This is a minor update correcting only the stated issue, I still have a little trouble with the bots falling off of the catwalk on occassion, but until I can figure out what they're trying to reach when it happens a fix may be difficult.
