To that guy from oct 2020, Hey o it’s me that guy who wrote the conv. Method, (blackout is my name btw) um the method is still functional and I jus tried on my single player casual save and the method is still working. I don’t think that the method is broken but here are a few things to note.
1: ONLY works on casual
2: Most servers aren’t casual
3: you may have forgot to take out the normal polymer
Dont eat it, tame a decent moschops and level it up, hold E and u can find harvesting levels and put all points on to organic polymer. Tame a couple (male and females) of penguins and make them breed and kill all the babies with the moschops.
So much easier to get heeps of polymer very quickly is to tame a decent level moschops (this is easy unless they require something you don't have). Put all the harvesting levels into polymer gathering and go kairiku hunting. For pc use c to harvest. I got thousands of polymer in less than an hour doing this.
