Not sure what's happening right now, but the tracker is down at the north end of Thirlmere, having dropped down that side from Armboth Fell rather than continuing to Borrowdale. Must have been a difficult night as she was still about 6h30m up at Portinscale, down to about 3h30m at Armboth. Not clear whether it's just the tracker down there or Sabrina herself, hopefully the former!
