Getting really tired of the bugs in this game. They make an otherwise great game unplayable. I just now found out that invisability potions don't work. I pop one and enemies keep attacking me without fail as if im still visable. I try sneaking while invisable and archers keep shooting me, sabre cats keep hitting me and soldiers keep following me. I am unsure if there is some mechanic I am missing, but I would like to think that I would not need high skills in sneak for INVISABILITY to hide me from sight. From what I am seeing it works more like chamelon in oblivion but much, much less effective. I can not imagine this is how it's intended seeing as you can not attack while "invisable" without being made visable.
So add this to the list of things that make playing a mage unplayable, along with no regen in combat, spells that don't scale with level, and all the great spells like unlock and waterwalking being removed. This game was clearly made to cater to the brainless barbarian type that just grab weapons, spells, armor and whatever they find; equip them all and slaughter everything without thinking about their characters, or playing a role. Totally not TES game material. This game could be so great.
