It's a really stable script, except it's really slow, at least for superglass make and humidify. It is about 50% slower than I can do it manually.
This is how it runs:
open bank -> deposit & withdraw material -> press x to close bank -> press magic spell book -> casts spell -> press inventory (this step should not happen as it should stay on the spell book at all times, loses 3-4 seconds total) -> repeat
More efficient way:
open bank -> deposit & withdraw material -> use ESC to close bank (save 2-3 seconds) -> use spell -> repeat
If you were to make these changes then it would probably boost the speed by 20-30%.
