Very odd Pacer behaviour today. I joined Yumi in Douce France from the home screen. I got a screen message that the route no longer existed, but I was dropped into the Yumi group. The mini map showed my progress, but suddenly the group took a different turn to me. So I teleported back (got the same message that my route choice no longer existed) and continued with Yumi. This happened about 3 times in the hour ride. Not a big deal, but a bit tedious.
