I have multiple evolution stones and have tried to use them on many pokemon, but to no avail. I've had this happen for a water, sun, and fire stone. I first tried it on a Cloyster with a water stone and I right clicked it. Then I tried it with a Gloom and a Sun Stone and I did right click it. I finally tried it with a Growlithe with a fire stone and I once again right clicked it.
