Endless loading screen - even after updates

Hi!

I've come across the same issue as many others apparently - that after installing the toddlers update I am unable to enter any lot using a family and just get an endless loading screen. Even though i only wanted the toddler and vampire pack, i followed the guides and installed the rest of the available new expansions (fitness pack and toddler stuff, parenthood), as well as applied the fix for the errors and moved the The Sims 4 folder to the correct location. HOWEVER, i am still getting the same endless loading screen. Is there any way to fix that?
My base game and previous expansions might not all be from games4theworld, i'm really not sure, but I don't want to waste so much time re-downloading all of the expansions/games from your site and reinstalling everything, as well as losing my currently played games and all progress. 
Is there any way around this? Or have i been doing something wrong?

Thank you in advance!

I have the same issue. I hope it's fixed quickly! 

I think I fixed it. Had to reinstall the entire game, I think the problem was that I hadn't renamed the folder after installing the vampire update. The game is a bit slow now, but works. However, there is a glitch, one of my toddlers is constantly asking for a bath, every interaction is just that. Not sure how that relates to the update though.

Hmm, interesting... I've done that from the start and still has the problem with the lots.

Aren't there a "reset Sim"-cheat you can use in TS4? Perhaps that could fix your toddler
