Unable to complete altar with 3rd potion

Have 165 primordial ashes, cannot complete the 3rd potion (despite it having a cost of 165 primordial ashes).

This completely screws the game’s mechanics up for s28.

Terrible programming from Blizzard.

NOT a happy camper. Will try a 2nd character and close the game down and start it back up, but I don’t like my chances.

Are you sure you have unlocked both nodes connected to it (Carrion and Reaper)?

Either is enough, it does not have to be both.

Update: I thought that I’d not unlocked father, but it turns out that I’d already done so. The weird thing is, the other 2 potions were highlighted…and those were the 2 potions that I was sure that I’d enabled the night before last night.

Either way, altar now fully unlocked. Had a primal drop 5 minutes after unlocking the altar and had 2 primals drop. Reforged a HPS quiver and got a perfect primal on my first go, so very happy.
