I'm new to all of this, so this may be a dumb question. Are the original forms of the supposed to be alternate Pokemon still in the game? I keep trying to redownload the patch, but in game I keep coming across the original forms and typing (i.e. Skrelp is still Water/Poison and not Water/Grass). Are both forms in the game and there is just a chance to come across the other forms? Please help. Thanks. Also, does this pack work with the randomizer mod? Maybe that is the issue?
