I bought double tear of the goddess on midalee a few games ago (we were really far ahead and not afraid of losing) and I charged them both up to full. I then went to upgrade one of them into the archangel's (which is then automatically turned into a seraph's something) and then I looked at my other tear and it was back to 0 charges. Not sure if this is intentional, just wanted to make sure.

That hapened to me too i was playing karthus ona Proving grounds custom game and i started to buy tearof the goddesss . every time i used an ability alll of the tearof the goddes where proccin their passive

It's more of a tooltip bug. You're supposed to be only able to charge one at a time but it shows as if you were charging both and when you upgrade one the other one properly updates to 0.

Ah ok, that makes sense. Thanks for the reply guys. Just wanted to make sure it wasn't a bug or something.
