I of course can't say for sure without testing the code myself but this
almost certainly isn't a bug.  Your simulation simply got instable.  Your
animation shows you are using very stiff connections and therefore you
need quite small time steps to successfully simulate the movement.  Try
doubling the number of steps and if the problem vanishes this was the
reason.  

The next version will contain a test function which tries to detect
instability and issue an Error.  It seems to work fairly well but of
course there is no guarantee that it always works.
