Notes:
1. I encountered this issue on PC (windows store)
2. I was playing alone
3. I was playing as wulfgar
4. I played for a few hours and my health Potion was working normally, then after upgrading my health consumable and changing the equip slot my heath Potion became bugged. Ever since then whenever I drink the Potion it does nothing / does not heal me. I noticed that the description for my health Potion had changed ( see attached screen shot) it also shows my health usable as level 1 when I have already maxed it out. Also when I made a new character the Potion worked normally again, so only my main character is bugged out.
