Good List. Xur once forgot to sell a gun. Engrams sold by Xur used to cost Motes of Light, not Strange Coins Guardians used to drop Heavy Ammo when killed. You could die and still pick up the Heavy Ammo allowing for Heavy Ammo 2 minutes after it had been launched. The Special Crates used to have a 30 second timer rather than a two minute timer. There used to be 7 Special Ammo Crates per map, now there are only 4. Public Events used to grant packages in the postmaster. The package is now automatically applied after completing your first gold one in a day.
