track & route breaks the web planner

You (LM devs) may be interested in a combined track/ route in which you can see the displayed Slope is perfectly flat on top - weird!!

The first 35km is correct recorded track data. At this point I paused the recording. When I unpaused it an (approx.) hour later I forgot to disable battery saving, so there was no further track recording. BTW if there had been a message in satellite view like at the startup to remind me, I would have disabled battery saving, but I digress. After the end of the trip, and for the rest of the "track" I went into the LM4 Android route planner & fudged the track as a route so that the complete distance was accurate - better than nothing. BUT when I view this now combo zombie track/ route in the web planner it gets quite confused. There was even a time (can't reproduce) when the hover tooltip of the bottom chart "locked up" & wouldn't further respond or move. I just thought you may find the data of interest.
