On part 2 of the Celebi questline, I can't progress past the part where Scientist Alexander opens the G.S ball.
I have caught all non-legendary Kanto + Johto pokemon, and have seen data for every pokemon up to Celebi, and have 129 evolutions and I'm johto champion with over 150hrs playtime - but Scientist Alexander still tells me to leave him until he opens it.
Could somebody tell me what I'm missing, or if this is a bug?
