Well it appears that something must be happening to that state folder on every flight, or at least on the last several flights, because I have the same problem when I quit x plane, restart it and click on new flight with the tbm. I assume the state folder holds the state of the switches, covers, and what not from the previous flight? That being the case I guess, and unless you have some other suggestions, I will just need to start a new flight with a different aircraft and then switch into the tbm after the first aircraft loads. That seems to work although it adds some significant loading time since it requires the time to load two aircraft. At least that way I maintain the state of the tbm.
