gta online - How long does a crate drop take in Grand Theft Auto V? - Arqade: "I'm pretty sure the normal crates spawn randomly when it comes to time, and if you go to the drop impound right after it shows on the map the crate will never spawn, I think it's a bug because one time I did that and I waited 3 real life hours, and one time when the inpound spawned I waited one ingame hour and the crate spawned."
