Game is unstable for me, too. Is it just me or do cryptarch rep rewards become trash after rank 30+.Leveled him 3x and got the same items. Blue chest and blue weapon over and over, been like than since I hit 30s.
On the up side. All the blues that I saved up (around 23) converted to all blues and one legendary. Maybe someone done goofed on the patch only affecting post patch items.
