Finally installed Snowfall and Natural disasters, so I'm running all the paid DLC.. man, the fan in my computer is flat out!
After 2 hours or so with the DLC's installed, the natural disasters add on decided to hit me with a 7.7 magnitude earthquake.... despite having switched off the actual disasters element of the pack. I wanted it for the additional services (helicopter first-aid and firefighting are a lot faster than the vanilla options), this killed one of my Campus DLC universities, and the surround area... I opted to go back to a previous save

.. be careful with the ND DLC if you use it.
EDS just got updated, which sent the equivalent of a death wave through my industries... annoying since it hit the vanilla Industry (and OFFICE!) zones, which the EDS doesn't control
Lost a good few thousand citizens tonight, and bull-dozed a lot of buildings, including many growables that I placed by hand, which had become abandoned....
