Microsoft Flight Simulator 2020: TERRAIN SPIKE at KFHR

Here we have the SU15 installed and Friday Harbor listed as an upgraded airport in SU15.
Unfortunately the odd 'long freeze' -an episode where FPS drops from 45 down to 3 and the simulator freezes for more than 20 seconds - when you cross the channel from KORS directly toward KFHR - is STILL a problem. It has been since FSX. Only now there is a very large terrain spike just to the right of KFHR to go with it.
This flight was flown in the updated JMB
