Which card did behave improperly ?
Skeletal Scrying

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
Manalink 2015/3/25: Fate Reforged,duel

What exactly should be the correct behavior/interaction ?
Skeletal Scrying no crash

Are any other cards possibly affected by this bug ?
-

removing Inquisition of Kozilek from AI's hand prevents assertion error.

So,does removing Skeletal Scrying.

Even if already confirmed, I just wanted to add that in a clean game crash also happen with Skeletal Scrying + Dark Ritual only

I actually found out a bug: Skeletal Scrying could be cast with X = 0, but the actula code won't allow it. I fixed that in 4169fb2, also improving the code a bit. Consider this fixed until further notice.

It still crashes frequently when AI considers to cast it.Like this one produces a dump error and then a Microsoft visual C++ Runtime library error and finally crash.

I think it's fixed in 900c8f0; Aswan jaguar, can you confirm?

I still get an error. AI cast it successfully once the next it crashed.

Ok I see, thanks. 958cdd8 should definitely fix it then.
