This hasn't happened that much when it was seemingly introduced in Summer Camp but oh boy is it annoying when it happens. I have 2 full clips of me demonstrating all item physics not applying to anything in a public match but unfortunately Discord's scummy ways don't allow me to upload videos that big unless I pay.
So basically, when I throw an item it freezes exactly where I am, when me or someone else unlocks a lock it floats there instead of falling down, and breaking down blocked door doesn't push the chair away like it should.
