The issue there is that we were tweaking the issue with GPS spidering for accounts with challenging home port GPS readings (metal coverings, etc.). We were tuning the radius up of what it means to be “back home” at the location where the trip started. Where you stopped for your anchor break was within that new, larger testing radius. So when you were stationary (at anchor) and within 500 meters of where you started (large radius), it marked your trip as complete.
Have to tune that upper bound down, but we need to do that as part of better smoothing and outlier detection, which is in progress.
