I am sorry if I'm posting this in the wrong forum, I didn't see a "bug" discussion forum, so I thought general was probably the second best place.
I'm only posting major bugs, game ruining ones, so that they can promptly be fixed and no longer abused/exploited.
The main one is that bone walls can not be destroyed or stolen by spell cards. I'm pretty sure this is just a bug, but when you destroy (say with Deflagration) or steal (with Steal) a bone wall, you only take one bone. This has to be a bug. Pretty much the only thing you can use to destroy bone walls are massive amounts of different monsters at once, as any deck that uses one is going to have ways of killing plenty of units to give it charges (yours or their own).
Bone walls should be like any other shield in that Deflagration or Steal complete removes them. They completely nullify decks with a few powerful monsters and in that way ruin the game for those decks. Please fix.
Another large bug I've noticed is that when you click on one of your monsters to use an ability that targets something, if you choose to cancel it two bad things happen: Not only do you lose the element cost to use the skill, but you also lose the ability to CAST the skill even though you didn't even use it!
Please fix these two things.
Thanks.
