Khaine playing DF Experimental:
So I'm going through progression.xml for Butchering tools lvl2, perkbowweapons2... and it says requirements are reqweapons4 - which means i leveled to lvl80 unlocked all crafting perks to lvl4 ( weps, tools, guns... ) yet it still says I don't meet the requirements? According to progression.xml this should be it - so what am I missing?
Side note -
you did a superb job in balancing the pack - best by far, but

it would be even better without any level gates ( personaly I prefer "gates" behind skills progression or combination of those.
Also if you find a book recipe than recipe should be unlocked, but materials like steel for example are still locked behind normal progression, which means you either buy them or find them elsewhere salvaging etc. I know you are limited by TFP limitations, but I think these could be done.
One more - last one I promise: generalschematics should have higher drop chance since they are the only way to make mods. Day 19 and I only found 5 of those after looting 2 Bookstore towers and 5 big libraries ( QualityJoe 5/5 ) - I have only few mods that I found in loot boxes, but mostly for tools. Maybe a little tweak here would be nice, since recipes requires from 5 - 10 schematics for a single mod.
Great playthrough so far, you really balanced the perks and gameplay spot on. ( with few tweaks perhaps as mentioned above ).
