missing assets in brindleton bay

yaanaplays  Please do a clean uninstall and reinstall of Sims 4, as described in the accepted solution of this thread about a different issue:

[CURRENT ISSUE] Sims 4 DLC shows as installed, won't load in-game | EA Forums - 11831673

Anchors don't work on this site at the moment, so use ctrl-F to search for "revo" and jump to the relevant section of the solution.

I would suggest that you reinstall the game (and the EA App) while in a new admin Windows account, to be thorough.  You can create one for just this purpose.  Make it local, as in, don't link it to your Microsoft account or any email address.
