There's a bug when certain objects are scaled to be smaller or larger than the default size—the object won't sit flat on the floor. In the first Storymode mission, I noticed the bug present with the nightstand (when scaling smaller). In the second Storymode mission, it's present with the fridge (when scaling smaller or larger). The smaller-fridge actually glitches visibly when you move it across the floor, as if to place it; you see it sit flush against the floor's surface then it jumps up.

My guess is that the object believes it's still the original size, when it's been scaled smaller, and that's why I see the empty space under the fridge. Similarly, when the fridge is scaled larger, its bottom actually goes through the floor.

There's no way to adjust to make the scaled-object sit as it should on the floor, even if I change camera angles and move the mouse carefully.

I'd love it if the developer chimed in on this, because I'll happily resume playing the game once this is fixed.
