I am having issues too with my game since yesterday - I downloaded the cool kitchen stuff pack, problems started a few hours after. Also have cats and dogs, no more add ons. Checked the fan of my PS4 - no excessive amount of dust there. There is still 400 gb or free space on my internal drive. If my sims just get stuck the resetsim option fixes tbat. The game also completely freezes while playing at random. The only thing I can do then is press the home button and close the application. Already re-inatalled the game and added my backed up save game, only the one I am currently playing with. Deleted loads of things from my library - only one household, 6 lots and no rooms left.
Version installed:
BASE: 1.10.33.4400 (64 Bit)
FP01: 1.assets.live-fp01.52
SPO3: 1.assets.live-sp03.50
EPO4: 1.assets.live-ep04.15
Please help!!!
Edit: the freezing of the entire game seems to occur more when I use the speed up time options.
