A new problem arises.

While I'm able to modify the type and amount of skill requirement of most weapons, I can't change the skill amount for homemade(crafted) weapons.

For example, in vanilla, the lowest tier of Homemade Spear requires Strength 9 (even though in the txt file it shows Strength 7). I try to change it to Dexterity 7, and it'll change to Dexterity 9. The skill type changes with my mod, but no matter what number I put, the value ingame is always 9. Same with other crafted weapons. Their skill requirement value is 2 higher than the value in the txt file and cannot be changed.

Non-crafted weapons don't have this issue and their skill type and amount can be changed at will.

Why is this exactly and what can I do?
