Sphere of Safety bug

I have trouble every time Sphere of Safety or any similar effect is played. Sphere of Safety adds a cost to attacking; any time a creature attacks with it in play, the game doesn't know how to handle it and crashes. I've also noted this bug with Norn's Annex. I haven't tested it out with Ghostly Prison or other similar effects, but I'd imagine there would also be problems.
My apologies if this has already been taken care of. I'm not even sure if I'm using the most recent version; my version doesn't have the two most recent sets, I think.
