I have also had this bug for about a year or so now, and I agree with the comment above - I can't believe that it hasn't been fixed yet. This is an absolutely crucial part of the game for me, and it affects both CAS and builds. It has put me off playing the sims and buying new packs, because I can't even favourite builds properly, so therefore the Sims is losing out on a lot of profit from me in particular, and I'm sure a lot of other people because of this bug. Two years is absolutely ridiculous, this should have been fixed within weeks of the first reports. Please fix it, otherwise you will continue to lose out on profit.
