I've got the problem that my health potions in my interface were not visible. I've already tried to sell them all and buy new ones but they still were not shown. There is only the black background with a zero even though I've got about 120 in my inventory. I've got the problem only on my Witch Doctor.
Hopefully someone understands my problem and knows how to solve it. If it's needed, I've uploaded my d3save so someone can have a look at it.
Maybe it is possible to unlock all acts for all difficulties for my monk, too?
