I found her the pidgey she wanted, got all the trade dialogue, and then at the end of the conversation I still have my pidgey and not her Oddish. When I talk to her, she asks how her oddish is doing. Is this a known bug?
Edit: Checked the PC and Oddish is there, but I do still have the pidgey (in my party); so maybe there's still a bug? I had the pidgey's stat window open during the trade, maybe that glitched it? Ended up with the IV Pidgey and the Oddish.
