This bug if really weird because I played TS4 yesterday with no issue whatsoever (I updated as soon as the update was available) and today, yeah, rain inside the house, also in Henford, don't know about other places. It doesn't seem to be affecting my sim, ie, getting her wet/uncomfortable....yet, but still annoying
