[confirmed]Doublestrike+multiblock=bad forced dmg assignment

[Korath]

Describe the Bug:
If I block with a creature with double strike and a multiblocker, and the double striker kills the creature it's blocking during first strike damage, I'm forced to assign damage during normal damage and can't.

That's another Crazed Goblin in the AI's graveyard; it was blocking the Mirran Crusader. Foriysian Brigade, for autocard reference.

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
Post-BFZ dev. Bug as originally reported in Shandalar.

What exactly should be the correct behavior/interaction ?
Nothing. And the presence of the multiblocker really shouldn't make a difference, but it does.

Are any other cards possibly affected by this bug ?
Original reporter claims it happens on attack too. I haven't yet puzzled on a scenario where that happens.

Also happens for non-double-strikers that block, when the creature they blocked has left the battlefield (say, due to Unsummon), so long as there's another creature multiblocking. Pretty sure this would've happened with Two-Headed Giant of Foriys all the way back to the original MicroProse release of Spells of the Ancients; how come it never got noticed until now?

Probably because by the time double strike came around noone was using the two headed giant anymore.

Double strike is just a way to exercise the bug (which is solely in multiblocking). Anything that removes the blocked creature from the battlefield before the appropriate damage step makes it show up.
