No Revives Glitch?

[phantomness]

I'm not sure if it's a glitch or not, but when I battled Shirona, I was unable to revive my pokemon with the item 'Revive', even though I still had 11 revives in my bag. Other items still worked, like Full Restore, just not Revive...

Perhaps a move, item or ability is in effect.

... There's an ability that can block the use of items?! I couldn't find one, nor an attack that would affect items in the bag, only hold items, and none of my pokemon were holding Revives. And it doesn't prevent the use of other items in the bags, just Revive. Very bizarre.
