Ninjutsu in Forge 1.2.11

Still testing the Sealed Deck mode in Forge 1.2.11, I came across this:
I have a Hurr Jackal in play and Okiba-Gang Shinobi in my hand. I make an unblocked attack with the Hurr Jackal, ninjitsu in Shinobi and return the Jackal to my hand.
What happens? A tapped, summoning-sick Shinobi completes the attack succesfully...and deals 1 point of damage! (Like a Hurr Jackal would, instead of 3 points + discard 2 like Shinobi should.)
