Thankfully 343 fixed Stockpile never showing up in Reach, but now they need to fix the problem that Breakpoint doesn’t show up! This is my last achievement I need for Reach (until the new maps come out), so come 343 fix this problem!
Breakpoint will only show up if everyone in ur party has the Noble Map pack, that includes the other team.
For some reason most people who search in Invasion have not purchased the maps, so yes it is frustrating, but not 343’s fault.
