A quick note, im passed the kalm town. When yuffie scene comes, when choosing party members don't choose anyone else besides tifa and aeris, otherwise aeris and yuffie will get stuck after battle. This is surely related to phs cheat. Probably the same with barret. After i kept tifa and aeris in party during battle, yuffie joined wo glitches.
