My SIM was at university when I applied the new patch. No Mods. Loved the new inventory system at first! Finally some way to organize!
After playing for a couple of days, 3/4 of her inventory disappeared. All Strangerville content, all books (including university textbooks and homework), crystals, pimped out laptop, bike, etc. You get the idea. Very upsetting. Can even check the household inventory to see if maybe it went there because, well, it's University. My SIM hasn't graduated yet so I'll check when she does but I'm not hopeful. New development- the "portable computer" does not show in my SIMS inventory. She was at the library and she used it independently. My guess is that all of those objects that disappeared are still in her inventory but just cant be seen for some reason. Before anyone asks, I cleared all filters applied to the inventory items (first thing I checked).
