Using a computer, push scaffolding, carts, chairs, and arcade cabinets no longer makes you drop what you're holding, even if your hotbar is full.
The item in your hands when the game saves is now back in your hands when you load instead of dropped.
Burst pipes no longer happen once almost all of the egg's shell is gone, since there's no shell left to patch them with. Any flood that was already stuck in a save like that stops by itself.
Closing the pause menu during the dream sequence no longer locks your mouse to the center of the screen.
