Bug: Haste Potions can't be brewed with redstone or glowstone IGN: Blendyz Date of Bug: 9/22/2018 Summary of Bug: If you try to brew a haste potion with a glowstone or a redstone you just get a thick potion or mundane potion. I believe this is not intentional but it needs to be fixed. You can't even make a potion of dullness into a splash potion. (What is the use at this point?) Evidence of Bug: Additional information: I spent countless hours grinding alchemy just to find out that haste potions are practically useless. Please fix this asap.
