Fixed: a GPS freeze that stacked a whole walk on one pin
A stalled phone GPS could keep reusing a stale fix, stacking a whole walk of trees on one coordinate. Stale fixes are now discarded, a watchdog recovers a frozen GPS, and untrusted captures save without a pin.
This was the big one. Your phone's GPS could quietly stall and keep handing back the same stale fix, so a whole walk of trees landed stacked on a single coordinate. We found it in real field data, confirmed a case where it stalled for roughly 50 minutes, and fixed it at every layer.
Stale fixes are now thrown away, a watchdog restarts a stalled GPS within seconds, and the location chip honestly says “searching” while it recovers instead of pretending it knows where you are. If it ever cannot get a fix it trusts, the tree saves without a pin so you can place it yourself. No pin beats a wrong pin.
