Lits in Build Mode reset upon entering Manage Worlds

I've been playing the sims religiously for awhile and finally filled out newcrest, but after the newest update the games become unplayable. I load in, enter build mode on the lot im currently building on (shows that MY BUILD is there as i left it) but when i load into build mode suddenly the build has been completely deleted and replaced with the default lot that was made by EA. My gallery wont save, and every single time I try to build this happens. Ive already removed all my mods and cleared my cache as well as restarting the EA app. Ive spent almost 900 hours in this sims save and I would hate to lose every pixle of prigress because an update destroyed the game again.

Mods removed, cache cleared, app restarted, nothing different. I do not get error codes, it just wipes my lot completely.
