The only things different I can think of are all the kids in my previous generation & the 1st kid in this gen were adopted, and I hadn't been playing much during the previous generation (just checked quickly before bed basically). Not sure why/how those would affect the weather in my current gen though. The strobe light lightning happens every time it rains now. If there's bottled weather for sale that does stop it, but also stops the rain (making bug collecting problematic I fear). I do have the free food glitch too (started several generations back) but um, I'm ok with keeping that one, lol.

I noticed one other rather interesting quirk today though when I gave the kids a movie to watch. The little girl I gave it to walked out of the room with the tv (which has a couch) and sat on a couch in another room that didn't have a tv, but her status still said she was watching tv. Rest of the family went to the tv room, perhaps their little girl just has x-ray vision!
