@ Metropolis Man, Thank you and good morning
I'm currently using the LN bed that sells for 4k. It was virtually unplayable when I was using the cheap brass bed that came with my house. I don't recall the name offhand, but upgrading the beds, showers, stove/refrigerator was a priority early on. I'm a bit of a purist, so it had to wait until I could actually afford to do it without cheats, and that was fairly brutal.
I'm still getting moods in the OMGPMS range for no apparent reason. It's incremental and nearly imperceptible immediately after restarting the game, but begins to negatively effect job performance and interpersonal interactions within an hour or so. Much longer than that, and it's time to call in the maid/repairman to sort everything out and clear some of the negative moodlets that render my Sims nonfunctional.
It's a VAST improvement over what it used to be, but it's still rather vexing when sending a Sim to work decreases their overall job performance. As I tend to get sidetracked (or bored) quite often and start new families, it's an issue I deal with frequently enough to look for a more permanent fix than restarts... or perhaps switch to decaf and see if I can stick with one family for more than 2 days... see if it resolves itself... lol
