Hulk Smash No Work

Unknown

I was just doing the Hard Simulator Essential node against Xforce, Cmags and Black Panther; this is what happens.

1. I down Xforce by dropping Lazy Thor's Green on his head. This leaves BP on 5777 health and Cmags on 777 health.
2. I have enough Red to drop Hulk Smash on both of them and enough to kill Cmags before he can use his blue power.
3. Use Smash, Hulk goes through the animation and not a single thing happens to the enemy. I lose the appropriate amount of AP from red and green.
4. BP proceeded to waste the blue AP on Defense Grid.
5. I match Cmags to death and follow it up with Thor's green.
6. I kill BP next turn.
7. I win.
8. I come here to report Hulk smash not working.

tl;dr - Hulk smash did no damage.

Has this happened to anyone else? Probably just a one-off.
