don't just say 2.1 or 2.0 it sounds like you're refering to podbot 2.0 or podbot 2.1...
more correctly it should be podbot 2.6mm R2.1 or R2.1 for short.
The 'R' helps to distingush us from the original podbot, since we are not the official maintainers of podbot..
We're only coding for podbot 2.6mm which is PMB's metamod port of podbot and cleaned by PMB.
And this bug has existed since PMB's latest release..
you can even check yourself.

The only thing that your info matches with, is with what PMB did to the Podbot waypoints and that is, he corrected what was saved when making camping waypoints.
in the original podbot the bot saved a vector in the direction the waypointer was pointing at.. (at least I think thats how it was)
when PMB fixed it he made it save an angle instead of a vector and the angle is the angle where the waypointer was pointing at when he made the camp start/end waypoint.
