Runglaive Purchase Bug

Just wrapped up a bot game as top Ekko. I had TP and Flash as my summoner spells, but I noticed that in the build for sheen, the jungle items with enchantment were available for purchase. So for shiggles I tried to buy one, and it actually let me. Problem. It deleted the sheen from my inventory, took my gold, and I got no item.

So the Runeglaive enchantment apparently hasn't been coded to only work for Smite, or it could just be for bot games, I'd have to look in a normal game to see if it works there. Point being, DO NOT purchase Runglaive enchanted items if you don't have smite.

Update: I attempted this in normals blind pick and the same thing did not happen. So maybe it's just a bots thing?
