Now, I know there was a game update today, so you’d expect to get a few errors with mods or assets. This particular error has been happening quite often over the past few weeks, and there are dozens of threads on the steam workshop and on a FB group I’m in where other players are complaining of the same issue. Some people complain that it happens on game load, others, like me, find that it happens randomly in the middle of gameplay, as if it’s caused by a growable asset somewhere in the city. And when it happens to me, the water and power zots go off above every building. 

It might be worth noting that just a few weeks ago before this issue started, I was having another problem where residential buildings would grow but no one would move in, and the info panel said there were 0/0 households. It should say 0/1 or 0/3, but it said zero out of zero. I solved that problem by disabling everything, and then re-enabling groups of mods and assets. I narrowed it down to Advanced Vehicle Options. Not sure why that mod would cause such an issue, but disabling it solved the problem. Could be coincidence.

It’s also worth noting that this happens on new cities in which I start the game, subscribe to nothing new, unsubscribe from nothing, experience stable gameplay for hours, and then suddenly, I start getting the error. Again, I think it’s a growable. 

But the error info has no helpful information.
