Do you have Mods or CC that could be conflicting/broken after the recent update (it broke many of them)? If so you could try removing them and seeing if that fixes it. Whether or not you need to see if it is Mods or CC, I would run a game repair. (Open Origin, click 'Game Library' then right-click Sims 4 > Repair Game.)
Also, did you try moving your family/household into the gallery (evict them) before moving into the house to see if that made a difference (vs. moving directly from another home)?
If all else fails you could start a new, fresh game (additional game don't overwrite your current game), then go to that lot you want to move into and save the lot to the gallery, go to your current game and download the one that you saved to replace the one that is being glitchy.
