several bugs that i have noticed

[jarjarpfeil]

I mostly use this mod as a tinkers construct addon, but I have noticed several overall bugs with the mod and would like to help improve it,

please note: I am running this mod in a large mod pack so some of these may be from interactions with other mods. However, I am fairly confident that many of these are from this.

1. When TAIGA is installed, the tinkers smeltery cant tell the difference between adamant and adamantine, forcing one to become the other (I want my 3,200 base durability pickaxes)
2. fishing rods don't vary in durability, and they don't take damage from being cast, only when they catch something
3. the recipe for making rails out of steel only crafts one, the vanilla one makes 16
4. the ore spawn rates appear to be extremely low, with copper being even rarer than gold
5. crossbow bolts bounce off-targets, dealing no damage. also, they don't work like crossbows as they don't hold their charge
6. arrows/bows all do the same amount of damage
7. bolts texture broken
8. arrows from this mod become vanilla ones when picked up

thanks for reading this, and please let me know your thoughts.
