Business Panel Doesn't Show Owned Businesses

I have been playing The Sims for over 20 years and I honestly have never seen the game in such a broken state. The issue I am dealing with is not just some minor bug. The rental panels literally do not show up anymore. Sims that previously owned multiple rental properties no longer have them appear in the ownership panel at all. If I rebuy a rental property, it temporarily appears, but the second I leave the lot or travel, it disappears from the panel again like I never owned it. The properties still exist in the world, but the ownership and management systems are completely broken. On top of that, Royalty & Legacy titles still randomly change or revert after traveling, These are core systems people paid real money for and built entire saves around. What makes this even more frustrating is that EA acknowledged rental/save issues months ago and admitted some fixes were only partial, yet there is still no clear confirmation that these specific issues are fixed. Meanwhile updates keep focusing on Marketplace features and monetization while players are scared to even update or load their saves because every patch feels like a risk. I have invested years into this save file and spent a huge amount of money on this game over time. At this point I do not care about new packs or Marketplace content. I just want the game I already paid for to actually function properly again without feeling like years of progress are constantly at risk.
