I got the same bug. I played my Warrior with Way of the Frog to put it on my deck after discard.
Then I was prompted to exchange Warrior for Hero (because "on discard" was trigerred).
But I'm also prompted to "Execute" my Scheme->Warrior combo?
I understand that Scheme and Way of the Frog are very similar if not identical (minus the card draw on Frog). But what's really odd is that when I went for the Exchange and also tried to Execute, nothing got executed -- my warrior was Exchanged for a Hero and then wasn't on top of my deck
This seems to be an actual bug. "Exchange" should mean "replace the other card exactly where it is", so Exchange should just swap my Frog'd Warrior for a Frog'd Hero that I can get on my deck next turn. Instead my only options are to not upgrade the Warrior, or gain a Hero to my discard.
And of course, Scheme is not in the kingdom at all...
