Bug I Guess

Hello I have a big problem whit my build, basically when I use the auras they reserve my mana and health but in my build tree i have it set up as to not have any reservation of health or mana done. My friend is playing exactly the same build as I am and he dont have that problem. I have restarted my skill tree and I even was putting on his items same as he had putted on my items on his char and he has no issue whit it. But on my char I have a problem and I have no idea what to do.

Go there and uncheck hide characters tab and people will be able to see your gear and links.

Without seeing your characters, there's only two ways I can think of that reserve health: Arrogance Support linked to auras or Blood Magic keystone. But unhiding characters with that link above will help rule both of those out.
