Bugs keep piling up everytime there is a patch and new pack, I think that the best way to play sims 4 is when they dont have any updates for two months so that it gives modder the chance to came up with their own bug fix and then refrain from downloading any updates in Origin as to not introduce anymore bugs, I did made my own vampire bug fix that they introduced in Get Famous and only have been fixed a year later. I dont know what is going on in the studio but there must be some other devs who focused on bug fixing other than @SimGuruNick but the amount of bugs right now is unbearable I agree.
