in black 2 I was in the dessert town (can't think of name) and I went in a house where there is a old lady, karate girl and one other. The old lady sprite did not appear till I talked to the karate girl
Yeah, it is.
I wouldn't worry about it though, it seems minor. If problems seem to persist then your game is quite glitched. Sorry. :(
Hope I helped. :)
