I updated the items with base materials for quartz and crystal to match melone. It looks like there is some confusion since pbwiki wiki calls it "crystal (quartz)" but you can see they link to the japanese page called "quartz" (not crystal).

basically, almost all the items that were previously classified as crystal are now quartz...there are only 2 items that i have found that are actually classified as crystal in melone so far. snow crystal and sugar.

after checking the japanese version of pbwiki it looks like crystal is actually crystallization and there is only 3 items on there:

so...for now i have renamed crystal to crystallization just to make it more clear. there is no class now just called crystal.
