The Omni Sludge crystallization into Omnite allows for creating infinite Omnite right now with the highest levels of stone extraction and Omnisludge dissolution. You end up with more Omnite than you started with.
I'm too lazy to do the math, but maybe something like 60 sludge to 3 omnite (instead of 60->12) should prevent this while still giving some use to sludge dissolution.
