This glicth is with harralander when making unfinished stat restore potions you have the harralander as the 1st 7 ingredients you have it in this order 7 harralanders 7 Red spider eggs then your vial of waters when you use the herb on the vial of water the unfinshed potion appears but the herbs remain this is annoying for me as I expect them to dissapear. and it wastes good inventory space as they dissapear over time.
NOTE: it only happens if you do it in that exact order.
