@LKN I ran across something similar yesterday, but it happened about five hours before updating to v1.1.6 and it was all my aircraft logs which I suddenly noticed were gone. The only log entry I had was for the flight I had just finished and I suspect it was some issue with X-Plane rather than the TBM loading.
I back up my X-Plane to portable hard drives about every two days, so I had a fairly up to date Output folder with all log book copies saved, and it was not that big a hassle to get everything back up and current.
Anyways, as I said may be completely unrelated, this was well before updating to v1.1.6
Blue skies to you,
