Texture Glitch And Crashing (not tiles this time)

@poptartfromhell I don't see anything problematic in your dxdiag, other than the Sims 4 crashes themselves. And the fact that the new save runs fine means this is probably not a system or game issue.
Please make a backup copy of your main save. You can use "save as" to create a new save slot so you're not overwriting the current one. Go into HoB and bulldoze every lot where you've seen this issue, save, and quit. Load a new save, enter HoB, save the existing lots to your library, quit, load the experimental copy of your old save, and place the saved lots. Save, quit, and reload. Do you still see the issue?
I'm not saying you need to erase everything, only that this is a useful way to distinguish between different sources of error.
