This is frustrating as hell. I spend hours setting up a whole new build, save it and then when I come back I can’t equip it, in fact the first 2 builds can’t be equipped.
Edit: It seems the build itself becomes corrupted and can’t be requipped. I tried saving in a new spot but nope. Wouldn’t be so bad but reloading over 300 paragon points every time I want to switch is more than I can handle. It seems you folks just can’t get anything really right.
