Product: The Sims 4
Platform:PC
Which language are you playing the game in? English
How often does the bug occur? Often (50% - 99%)
What is your current game version number? 1.75.125.1030
What expansions, game packs, and stuff packs do you have installed? everything but Bust The Dust and the fitness fashion kit
Steps: How can we find the bug ourselves? Play a household, preferably with a lot of family members OR one vampire, make sure they're tired and make them sleep. Make the vampire hibernate in a coffin if you choose to use one, since nothing is supposed to wake them from hibernation. The sims I have seen the bug with all have decor-related Likes, aka modern furniture and whatnot.
What happens when the bug occurs? Sims will randomly wake up and walk to a piece of furniture, decor item, or even a window (usually going outside to do the latter) and view it. The little green "Like" happy face shows up with an image of the object. This bug will wake up hibernating vampires as well. They will do this autonomously even with autonomy off, and only the "resetsim" command will stop them from completing the entire walk-and-view action because there is nothing in the queue to cancel.
What do you expect to see? Sims should not be waking up to express how much joy they have that a build&buy object happens to fit the kind of decor in their Likes.
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? Yes
Please describe the patch or change you made. The patch that added Likes and Dislikes is probably causing this bug. I don't remember it from before that patch and/or adding decor-related Likes to sims.
I first saw this earlier today on a lot with one adult and 7 teenagers, and randomly some of the teens would wake up in the middle of the night, walk around the entire outside of the house, and look at a window. Now my vampire SuperSim is doing it on her own lot, waking up out of hibernation to go Like her stove or her pencil holder or whatever. The only mods I've been running are Basemental's Eco Hacks and "Get Famous_NoReactInDisgust"; I disabled them to see if the bug still happens and it does.
Update / Workaround: I removed my vampire's Likes in the decor category and she's hibernated three nights without issue. So it appears to be a problem with sims having decor style Likes that match objects in their house.
