Ihave been buying and collecting all the reagents for the rings of insight but when I go my home to make them it says I don't have all the ingredients. Also as I WAS collecting stone blocks and parchments they disappeared without knowing if they went to my backback or not.
You were pressing "x" to collect, not just running over the reagent icons and mistakenly thinking that collected them, I hope?
Are you sure that you didn't sell some of your materials by mistake to the Bazaar? Or use some of them to craft a treasure card before you got to making your rings?
