I'm not sure if behind the scenes the progress bar is actually as twitchy but inside the GUI, the auto-sieve and auto-hammer GUI animation isn't as smooth as it could be. This would be understandable if there wasn't enough power being fed into the machine, but even with more than enough power, the animation seems to stutter. Would be nice to get a cleaner progress animation.

On a separate note, some machine upgrades would also not hurt on top of the sieve efficiency, but the above is my main issue.

Closing since I don't think this is an issue anymore in the 1.20.1 port.
