Sorry for slow reply,
Yes I have located and Isolated the Auto save and Exit save on this game - Exit save 2020-07-05 00h21m, Day 24.
My population was only six missing Beavers,Not the estimated 22, but I have the Files all the same.
I also have a Auto save and Exception save for a sudden crash I have just had, 2020-07-08 22h08m, Day 129.
Thanks, Glen (Fardo)
