Is This A Bug, Or Am I Just Not Seeing My Mistake?

I wrote a script for a 16x16 turtle powered tree farm, each tree spaced out by two blocks. the turtle moves correctly if the first "tree" is only one log high, though it doesn't break the log, not that it's supposed to, but if it actually runs into a tree, rather than turning right after cutting it down as expected, it proceeds to move forward 5 block before turning right. the full program can be found here: http://pastebin.com/jwiWbGbb

Edit:

This is the intended path for the turtle, though most of it is commented out at the moment for debugging: http://i.imgur.com/u0Tz2ly.png
The grey square is where the turtle starts and stops, blue is the path, and brown represents the trees.

I should also clarify that I'm using CC 1.53

Split into new topic.

I've gone through my code several times, still unable to see anything that should result in this manner

If possible, could someone else just confirm that they don't see anything that should result in this as well, so I know it's some sort of bug?

This only seems to be an issue on multiplayer. Any ideas as to what might cause something like this?

Nevermind. had the server restarted and it seems to have resolved itself. please mark this as Resolved
