Freeze Dry

I caught a Cryogonal and it learned Freeze Dry but when I used it on a water type Clawitzer but it was not super effective. Then I used it on a Wingull but it was super effective. I am pretty sure that freeze dry will be super effective on water types, not just remove the resistance.

It is already on the bugs section ( https://bitbucket.org/PInsurgence/insurgence/issues?&sort=-created_on ) but you can post there again if you want to.
