I have to echo @Stormkeep I've played the game since The Sims became a thing and the issue of leaving things broken has also left a bad taste in my mouth. I've just come back after a long hiatus because I got so fed up with issues in TS4 that have been broken for so long. I haven't bought the Wedding Stories pack and won't unless it's fixed. I've hit the point that I won't reward a studio, any studio, for releasing such broken content.
I support the devs who work on this game and feel like they do care about meeting community expectations. I don't know where the ball gets dropped. I also think that QA works hard to track and correct issues. I support them, too and have provided many saves for encountered problems. My fear is that TS4 has become so big and complex with all the packs now available that it can't be completely fixed. I'm left with hoping that all major issues can be resolved.
