While purified water has a weight of just 0,10 per cup, firewater and other alcoholic drinks have 2,5 ? This makes no sense to me. Please check this. Same with orbs. An empty glass flask has 1,2 weight. A full glass flask (with water) has 0,20 weight.
Orbs (all kind of orbs) have a weight of 2,5 per orb. This is way way way too much.
