[Gameplay] Item auto-sold with no undo

Cannot so far reproduce. Was playing a game as Anivia and went back to base with a fair bit of gold. I completed my RoA (I already had two parts), and had a few hundred more gold and one open item slot. I very quickly double clicked to purchase a cloth armor and a pink ward before I realize I didn't have room for them...but I managed to purchase both. My RoA had disappeared and the slot was filled with a pink. My gold had diminished to the point where I could not repurchase the RoA. I also could not undo the purchase or sales.

Happened at 14:50ish of this game.
