Hi all,
I ran into the same issue with leg 12, but found how to bypass it and end the bush trip 
.
Yes indeed, when we look at leg 12, there is nothing defined. It’s a shame, because it’s a very interesting place, the Lofotten Islands. I know well … I went there a few years ago. So I’ll take you there 
The flight starts at Bodø - ENBO, but we do not know the destination. An indication is given by the orientation of runway 01, and there aren’t many like this in Lofotten. And if we look at the next step, there is no doubt that ENSH - Helle will be our destination.
How to fly from ENBO to ENSH ?
-
First you need to cross the large Vestfjord to join the south of Lofotten Islands. It’s simple, follow the Ferryboat line to Moskenes. Take off from ENBO, and head 310°. After 50 NM (about 17 minutes), you reach the east coast of the Islands , near the village of Sørvågen.
-
Now, turn right, heading 35°, like this, you will follow the east coast of the Islands, still in the Vestfjord. Soon after, you reach the terminal ferry at Moskenes. Continue heading 35°, and you reach the town of Leknes after 19 NM (about 26 minutes from the departure).
-
Turn right and heading 73° after Leknes. The airport ENSH - Helles is 24 NM far from Leknes, and you will reach it after a total of 35 minutes from departure. Land at ENSH and the leg 12 will be validated.
There is some fun things/bugs to notice about this leg and the Norway trip:
-
When you start the leg 12 from Bodø - ENBO, the airport shown in the window is ENGM (Gardermoen)
but it don’t care, you are really at Bodø, and the tower is the correct one.
-
The runway 01/19 at ENSH is short, and not flat.
As wind is from 270, I’ve tried an approach for rwy 19. 
OK, landed and Leg 12 is validated.
Fun to notice, that the leg is recorded as ENGM - ENSH, strange, but it works.
Now, the Norway bush trip progress is 85% 
Let’s continue the leg 13. No problem, the leg 12 is well marked as done.
There are only two legs left to complete the trip. Nothing particular to report for these, except that in the last, do not forget to pass next to the “Artic cathedral” at Tromsø (near the bridge, east from airport).
Now, you can achieve this trip:
And check that the progress is now 100%.
Enjoy
