Rollbacks after every reboot?

[Raymoo]

Something happened to me, a little bit similar, where my police building inside a biodome disappeared. It made me think that there was a much bigger rollback because most of my buildings disappeared from the city report. In actuality only the police station was gone. I'm not sure what this means, there were other buildings under the dome that were built before and after the police station, and many of them would also not be able to survive outside the dome. This was on a gas giant core. Afterward I installed a police station that could survive outside the dome, just in case. Not something new, this had already happened when I made my last post in this thread.
