That mesh is terrible...why don't you try creating a path that's larger than a single cell wide. How do you think that path randomization would even work properly on a mesh with paths so small that the bot can barely work out a single path to use, let alone randomize it. You should strive to ensure that the mesh never, ever has tiny single cell paths like that, particularly around corners and turns. Don't try to force the bot to run a specific path by meshing...the bot will determine the best path, the mesh should provide ample running room so that they bot has lots of data to work with when performing path calculations. When you mesh that way it makes it extremely difficult for the bot to determine a path and you end up with the navigation "problems" you're describing.
