I also had an idea to make a version of this with a new research that teaches you to make a "decrepit" version of every weapon type, but only of a rusted junk grade, with the cost of like 1-2 books.
So it would be like an early game thing, so you can start training weapon skills for heavy weapons from the start of the game without having to drop thousands of cats to be able to make them. But, ye, you would only be able to make rusted junk grades of these, if you'd want to make any better grade - you'd have to buy the bluepring for each weapon, as per usual.

The idea is that you'd flip through some Tech Hunter's lost log where he described each weapon he encountered in his travels and you'd learn to make crude imitations of these weapons just from the looks and the guy's comments on each weapon.
You know, lore.

So if you guys would like something like this - I'd make a seperate version of this mod with these "decrepit" weapon versions. (like anyone is gonna care about this mod, heh)

The reason I haven't just added it in this mod is because if the mod would happen to ♥♥♥♥ itself for some reason, or you would lose it in some way, all the training weapons you would have made, would just dissapear. I don't want to cause people inconvinience because I screwed something by updating a mod or something like that.
