We noticed in a 3/4-group today, everyone equipped with a reviver hive, that hive does not drop when going down. About 2 out of every 3 occasions (atleast 10 times overall). And if then someone manually throws his hive to pick someone up, they hive did not start to revive although it had line of sight (about 1-2 feet away).
We were doing 2 CPs and the manhunt with heroic & 3 directives active (No Radar,Special Ammo & no Armor Reg.)
Never had that issue before TU16.
