Marking this as solved since I didn't get any new reports
I have the same issue of autonomy disappearing and auto-solve no longer working. I posted about it in the Sims 4 forums as well. I even went as far as to start a completely new game and new household, but soon enough the bug occurred again. I tried the suggested steps of moving the Sims out of the affected home, saving the lot to my gallery, bulldozing it, then replacing the lot. Unfortunately that was only a temporary fix and soon after they all lost autonomy and auto-solve stopped working again. I never used the "Claim" interaction on a bed, but it seems that as soon as a Sim is directed to sleep in a bed they automatically claim it.
good call on the computer @Daugue I removed one of the mid-range 'Respecterion' desktops and it did seem to make quite a difference.
The other thing worth noting is that auto solve anything other than basic hygiene or eating, won't work if they're already doing something. For instance using auto-solve for a Sim with low hygiene will send them to the nearest bath or shower, but the auto-solve energy button won't work until they've finished showering/bathing. Although it can be very frustrating in large households, if you check on the action queue of all the household Sims, it could be that the idle Sim is waiting for another Sim to interact with them, in that case cancelling the other Sims actions frees up the Sim on hold.
