The "card" clearly stated Tristana. I had the gold but the bench was FULL, althought I had 2 tristanas already, so I shouldve been able to purchase it. I then cleared a spot on the bench, thinking it might be bugged. But when I purchased the character it was ASHE that appeared, when I clicked the "Tristana" card. Only happened once so far.
I've had this happen to me twice as well. I don't remember what characters but I do remember clicking one and receiving another.
I got a similar bug. I was trying to purchase a hero and it wasn't working. I had the golds.. -_-
I had a same bug happen when i was trying to purchase a karthus it gave me a morgana instead [slayer-jinx-unamused]
I've had it where it both gave me the wrong champ and a second card was missing next to where it was
