if you load up the previous auto save you'll notice the city is finishing the pioneer.
after that the pioneer get build and an autosave is created (without it in save).
in gameplay I built a city and got a crash to desktop (don't know why), you get the log anyway
however what's important is that when I loaded the autosave, I had neither the city nor the pioneer.
