So I'm at the beginning of johto, and I've just returned to this game after not playing for a few months. For some reason, I have 6 pokemon in my party (icluding my starter Cyndaquil), and when I try to deposit one in the PC, it wont let me. I also can't swap them out for any of my new johto pokemon I've caught. Please help!! TY!
