Lockdown despawning bug

Playing on Steam. 16:00 UTC, roughly. Dire Marsh trios, lockdown spawns in complex. We do the first lockdown and open the crate to loot, and we can't remove items from the crate. The crate then fully despawned along with the lockdown. A UESC rocket drone spawns at the same time the Lockdown disappears. We get a notification at the top of the screen to say Lockdown is now in Bio Research. We go there, and nothing appears until the match timer reaches 0. Lockdowns generally seem not to be showing up on Dire Marsh, but I suspect they might be getting broken by the Rocket Drones.
