Reviving conscious Pokemon in battle.

So, in a heated battle against the 6th gym leader, I was down to one pokemon, and I went to use a revive on my starter, but my finger slipped and I accidentally used it on the Pokemon that was in battle.
To my surprise, rather than saying "It would have no effect." like it does out of battle, it cuts to the battle, and I use up a revive on the fighting pokemon, having it say "It had no effect", then losing the fight.

I know your feels I've had this before...

Yup, this one's known and will hopefully be fixed in the next update. For now, I just advise being really careful when using items in-battle to avoid this happening.
