Sometimes the 1 default town is found again, but all rest of setup ( other locations, graph choices, F/C) all are gone. A bit annoying to setup all over again. Besides, F/C is not easy to find - in fact I spend 1/2 hour to find it after each upgrade. There used to be a "burger" on the right top corner - it cannot be seen again for about 2-3 upgrades ago ( it was faulty even then)
Great add-on but it needs work.
