I think there's an error on Mega Drain (move)'s page?

Question

I asked in Pokebase, and I think it is a mistake, the opponent doesn't have to be sleeping, right? Original question here:

Yeah my bad, I copied the stuff from Dream Eater I think...

Answer 1

I have fixed this now. Both Mega Drain and Leech Life said they only work on sleeping Pokemon, but of course they don't need to be sleeping.

COPY PASTA FAIL :D
