I'm a bit unsure of what you actually want to hear from us, but something I usually feel like is a problem when building would be the inability to move mirrors down (I think they're often placed too high).
It also bothers me how a lot of the kitchen islands have the storage on the wrong side (the side you sit at). Oh, and the debug catalog is an absolute mess to navigate.
As for gameplay, I find it strange how all decorations affect the sims positively, even if it's the wall cracks or cobwebs from Vampires, or the huge pools of liquid from Strangerville. I mean, it is good fun but also doesn't make a lot of sense.
Since these aren't bugs nor content requests I hope it's okay to bring up.
Now, for some positives: I'm very pleased with the trait updates so far and think it's great that they're being fleshed out more.
