A new massive update for SimCity released on Monday has apparently added a number of new bugs, much to the chagrin of players who have taken to EA's forums and Reddit to complain about them. The new bugs apparently plaguing the game after the v2.0 update include city sewage overloads, new traffic errors, a number of building construction issues, loading errors, and a few audio problems.
The update was meant to address some issues with traffic congestion, pathfinding problems and a list of other minor problems.
No doubt EA Maxis is working on the problems created by the update. We'll have more on this story as details become available. You can see the litany of problems (and add your own complaints if you need to) to this Reddit thread or in this EA forum thread.
