EA and Maxis have rolled out Update 8.01 for SimCity today.
The update contains education and tech fixes.
Here is what the developer had to say:
After releasing Update 8.0, we received lots of great feedback. Some players reported an issue after the update where some existing cities saw a sharp drop in education skill level, which put their technology industries into a decline. Investigating this issue immediately became our top priority. Thanks to your help and additional information, the source of the problem was located and a solution was created. Our QA team and DevTest participants has been working ever since to ensure the solution was successful and we will be releasing an update today with update 8.01.
