I've had this issue crop up over the last couple days as well.
I have one system where I'm trying to lay down a city and three colonies. The city rolls back to where it's no longer producing needed resources and the colonies roll back to being placed but unbuilt. I rebuilt the system 4 times yesterday before I gave up till today. City report looks like it reverted again
Had another city that lost it's city hall but not the police stations attached to it.
*edit ...
Upon returning to the city I had rebuilt 4 times yesterday, I found that a spacecraft factory, grocery, retail, and university had been duplicated leaving two buildings at the same locations. Deleting the duplicated buildings reduced the jobs the appropriate amount, morale stayed the same.

I plan on living forever ..so far so good!
