Enemy units behave normally, until they rotate, then their AI seems to break

I have a turn based strategy game, and the enemy have (very basic)AI. The little units seem to work and behave normally, but once they rotate, their AI seems to blow a fuse and they speed up, go through walls, and teleport randomly across the level.

I have been working on it for the last 2 hours, and had no luck, but as proofreading has always taught me, if you don't pick up on errors, someone else will, so I'm asking anyone to take a look at it and see if I did something wrong.

Again, I suspect that the problem arises from lines 59-96. To test the script, place it on a cube that is 1x2x1 dimensionally, and place it at 0,0,0, and place 2x2x2 blocks scattered in front of it on a 2 block grid.

Any help with this problem is appreciated
