That month or two was just a guess, could be later than that, could be earlier, only
Lykanz would really know(As he said theres a few more test releases planned), but Im not thinking its wise expecting anything sooner than that(People make expectations then always get upset despite devs not making promises, the fact his Patreons are getting to see these test updates is a good sign though).
Ive programmed before, and when you add in renders etc it could get a lot more complex and time consuming, I programmed a few things years ago that aided a local supplier for the oil industry, helped with health and safety etc.
