I had the same issue today flying into KDFW, logs attached.
I did use some time acceleration, but keeping a close watch on the nav display I did not appear to miss any waypoints as far as I can tell.
This lack of descent issue happens for me on most flights and is the one thing keeping me from being completely happy with PF3, all the rest is great. Hopefully a solution for this can be found.
Well you certainly seemed to have an interesting flight. When you were 103 miles from TYPTN (your 12th waypoint of 18) you hit terra firma!
You also requested a lot of altitude changes... from 34,000 to 37,000, from 24,000 to 23,000, from 23,000 to 17,000, from 17,000 to 13,000, from 14,000 to 10,000, from 11,000 to 8000 and from 9,000 to 5,000. All within a time period of 13 minutes and 100+ miles from your destination!
It then looks like P3D either crashed or you closed it down without first disconnecting PF3
