Autonomous Failed Pillow Fight With Llama Icon (no HSY ?)

Product: The Sims 4
Platform:Mac
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? 1.106.148.1230
What expansions, game packs, and stuff packs do you have installed? Horse Ranch, Werewolves, Tiny Living, Strangerville, Snowy Escape, Romantic Garden, Realm of Magic, Paranormal, Outdoor Retreat, My First Pet Stuff, Moschino, Laundry Day, Kids Room, Jungle Adventure, Island Living, Home Chef, Growing Together, Get to Work, Get Famous, Discover University, Cottage Living, City Living, Cats and Dogs, Bowling, Crystal Creations
Steps: How can we find the bug ourselves? Place a sleeping bag on a lot with only one Sim. Possibly drop the Sim's fun need.
What happens when the bug occurs? The Sim tries to autonomously queue Pillow Fight, but the icon is a llama and it immediately cancels, probably because there's no one available to fight with (I think I may have also seen this on a lot with multiple Sims when the sleeping bag was occupied, but I didn't catch the llama in time to confirm it was the same pillow fight interaction).
What do you expect to see? The Sim not auto-queuing actions that aren't possible - nor anything that would have a broken icon.
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. Installed Growing Together and got sleeping bags.

I've been seeing the broken icon appear and disappear occasionally for a while, but hadn't been paying it much attention at first. Over time I noticed it seemed to happen more often when fun was low, but not in all households. Then I finally caught one and saw the pillow fight interaction, and realized the households it happened in were the ones that had sleeping bags. Recently I managed to get screenshots from a mod-free save, which I'll add in an edit.

Edit:

Edit By Crinrict: Adjusted Title

Edit 2: Without High School Years, I only have pillow fight on sleeping bags, which I think came with Growing Together. I do not have any option to pillow fight on beds. I did test, and yes, it does work with both an adult and a teen, so it's not just for kids - and the icon should be the other person you pillow fight with.

When on a lot with a sleeping bag and no other person, they may still auto-queue pillow fight with the broken icon, but the option to start one manually is greyed out.
