I’m having a problem where sleeping doesn’t regenerate brain power unless I have them sleep from clicking the brain power button in the needs menu, and even then the sims don’t always go to sleep when clicking it, even after I’ve had them “recover brain power”
Apologies - I only just now saw your post (it looks like it got caught in Itch's spam filter). It sounds like Lot 51's Core Library isn't properly enabled in your game - I use that to add brainpower regeneration to all EA sleep interactions, as well as a number of other things. You'll want to double-check that that's installed, and in a top level of your Sim's 4 mod folder. If you've already done that, definitely double-check to make sure that script mods are enabled.
