[OPEN] Game 'freezes' occasionally when opening in-game menus

This happens to me to me to some degree when I click on a fridge on lots with a lot of objects, like on the mansion lots. It's been like this ever since we had the bug where they constantly made food and never ate any of it. But when I remodelled part of my biggest mansion, where my oldest and wealthiest family lives, and moved the kitchen to the other side of the building, the fridge lag was noticeably reduced, but it's still there.

Obviously I can't say if this is the same thing, but it seems like it.
