I just checked the systems.cfg (what creates the variables in state.cfg), and all the tablet variables are correct and in place. I checked my state.cfg, and all the tablet variables are also there, and set accordingly. Obviously, I'm not sure what else could be done, since everything appears to be in order on my end. Perhaps someone else will have a suggestion.
I thought you would also be interested to know that I have recently invested the time to create a whole new full state saving system for my aircraft, which may eventually come to the TBM 850. (I would like to. I just don't want to make any promises while I am still learning the capabilities of this new system).
