DarkSimzzz Some of the issues you stated happen in my game but weather inside my residential lots has been happening for 3 months now and B & H was not out. I know for a fact I am not the only one who's been watching this weather issue ?spread? get worse? affect different aspects of not only the older packs but perhaps changes were made to accomendate the new B & H pack? which has nothing to do with anything concerning the weather? or does it? I do not have Business and Hobbies and now, I refuse to spend another dime until my game is fixed enough to be "relaxing and fun" to play!
After investing the last 20 years into Maxis, Electronic Arts with Sims games, I don't believe that I am asking too much when I ask - Would you please fix my game!!! I supported you, now please, support me! If I mean nothing to you then I will humbly walk away! Ball is in their court and in the meantime , you could say, financially, I am on strike!
It started before the B&H update, I know because I have 1 PC that I haven't updated since Life&Death and the issue doesn't occur there at all ( BBB wasn't updated and I build a lot) , while on another PC I did do the update ( to get the event awards) and there it's snowing inside etc. It hasn't spread ? I think it was indeed actually an earlier update though, in January. That's where they added the new event and the basegame houses refresh. Still could be connected with the new pack regardless of that.
And my theory is that inside vs outside changed somehow for the pack to function, as they added new zones for residential and other buildings. Outside ( public), Public, residential, employees only.
I'll have to test with the pack to see if actually having the pack fixes the issue, that would be something jeeez. Even worse.
