Yesterday, during a hike on my 645 with latest beta firmware while running dwMap, the watch crashed while trying to change map zoom after 4 hours or so of activity.
I tried twice to reset and at the third attempt I just left the watch with the blue triangle on.
Eventually, after a few minutes, the watch woke up asking me to stop or resume the activity. Even though I started a dwMap bike, I was presented with my standard Running screen.
The issue is that it started to recalculate the training effect around 90-95% of the route: it gave me ridiculously low aerobic and anaerobic values even though I climbed more than 800 meters.
Before fixing the bug, is there any way to forcefully recalculate the training effort based on heart rate data? I may send Garmin the .fit file if needed.
