v1.2.1 massively fixed memory usage

changelog:

• reduced memory usage by like 400mb

as it turns out, the idiot who wrote all this code was a stupid idiot and massively overallocated where it wasn't needed, so i spent a lot of time making aggressive memory optimizations before realizing there were a few dumb mistakes that caused this whole issue in the first place. i hate arc, that dude is a bitch
