Loving the game next part needs to hurry up (replaying at mo)... So cos I know about the shells later did that at the prologue obtaining them so was prepared but once I got to that part and even tho completed that quest chain it didn't give me the achievement for it and first part of obtaining them was black crossed and not grey (like it's been completed) so couldn't buy one of the ai clothes
Addendum: tho it didn't compelte I did figure it out for the clothes aspect
