Our team was trying to pick up the heavy ammo.
Picking up animation completed several times but nothing happened. Eventually enemy team came by with their heavy weapons loaded and wiped us and managed to pick up ours.
edit: looking back at the replay, looks like the crate doesn't materialize even though it shows the notification "heavy ammo available"

Im not 100% sure, but that may of been a host issue. If you notice when picking it up, holding square stops just before its complete. Ive seen this a few times before, and it was always because of the host who would later lag out or be kicked from the game. As for it not materialising, thats also most likely because of the host.
