Pepper,
The waypoint tool works fine, but it is quite complicated and depends on a number of conditions.
Stay tuned on this thread:

And, I will try to analyse and explain all the important conditions that interact with the waypoint mechanism.
The waypoint mechanism is hard to mastered and it certainly is an advanced designing tool, but I repeat, that it works fine.
cheers,
Pyros
