I have been seeing this a lot in my testing save too. Sims are now abandoning cooking to go play on the computer. They also get queued to use the computer while they are eating, but they don't follow through and keep eating.
Another one is books. A sim will grab a book from the self, open it, then put it down. A few moments late they will do it all again. It's like autonomous actions aren't followed through. They never stay at one thing very long before being distracted and moving to the next. It is especially noticeable when you are trying to get your sims to have a conversation. The queues are constantly being interrupted by autonomous interactions with objects on the lot.
Getting water, washing hands and phone use is also an issue.
Playing on PC. No mods. No CC. All packs, except some kits.
