Just wanted to add my experience. I ran into the same problem. The runways (and by extension, the trigger areas) are moved with the FTX terrain. I had to resort to using the mission pointer to reallize that the trigger point for taking off from trout lake was not at all on the runway. Then when I flew into WN10, the runway wasn't just in the wrong spot, it was completely invisible! I tried about 5 times before I searched and found this thread. I had been thinking it was the PNW addon, but just didn't think to switch to FSX default. Did that last night and suddenly I could actually see the runways and complete the mission. Thanks a lot guys!
