This being grounded by the worldwide COV19 scare has awarded me time to dig into the various stuff in GP4 I was not aware of. Finally got all of my Zaz Tools working and like the various car/year mods along with working with the various track set combinations I've used for years. I cannot see how to set a car/year mod through CSM and have it retained while also loading a track profile through TSM (or vice-versa), When I load a track profile, run GP4 with it, close it down, and then "Start" a mod listed in CSM the track profile always wants to go back to the original default trackset. I'm sure I'm missing something minor. Advise fellas?
