A slight false start with the Cities: Skylines patch 1.0.7b whicH has been pulled for now but it can be used at your own risk according to PDX.
We are reverting to the last patch, 1.0.6b, until we have identified and fixed this issue.
Many apologies for the confusion and chaos caused by this!
Thank you for your patience and understanding. I will update you with more info and hopefully an ETA come Monday.
For users that still want to access 1.0.7b it is currently available as a steam beta – no password needed, use at your own risk!
