Since i have been crafting recently... (7 yr player just now crafting, i suck i kno ><) i wholeheartedly agree with crystals stacking to 99 and perhaps clusters to 12? i HATE having to carry around 7 or 8 inventory spaces while i'm trying to get none-stackable mats (currently goblin/moblin/bugbear masks) i end up throwing something away because i accidently fill up my inventory. Consequently, it would be nice if the afore mentioned masks could be stackable, you can stack hats in real life if you fold them properly so why not the masks?
