How comes the blank skill notes are rare? You get 3 of them every time you scrap any book or schematics, if you play with friends you should get enough really fast. And is it 120 blank skill notes you need on the writing station you need to craft a class book? I feel like it is less than that. And how comes you've got only five tires in 55 lvl? If you dismantle cars you should get them more consistently.
It seems like a bug, haven't encountered that. Well, you can just fix him, that's minor problem.
Lead is in snow biome because there is no burned one now.
