Sims 4 won't let me place objects

Any mods in your game ? 

Can you start a new game for testing purposes and try if you have the same issue ? Do backup the old one under a new name to make sure it doesn't get overwritten,

What error are you getting on trying to place objects ?

Ah, sorry. That error.

Usually happens if the auto save corrupts

Hi @LazyIavender

are you using any mods in your game ? If so, please remove them and try again.

If not, try repairing the game through Origin by right-clicking on the base game and choosing repair game
