Why the tree changes with your mods
Recipes are registered by the mods you load, so the same item can want different materials in different setups. This tree is computed from a dump of the recipe table for the mod set named above rather than written by hand, which is why you can switch sets and watch the material list move.
Coins are counted separately from materials. Terraria can convert between copper, silver and gold, so treating them as craftable turns a 15 gold cost into 150,000 silver coins and buries everything else.
