the animation of the container machines is not places perfectly.
when zoomed in a lot, the machine model will slightly move up/down.
i noticed this by watching the T3 machine with speed module installed.
it's just a few pixels off but it is noticeable.
This is an issue related to the incorrect alignment of some of the assembler's frames in the entity's spritesheet. Not sure hot to resolve it in a clean way other than refactoring the graphics. Only happens in low res
