Update: This issue also seems to be impacted by any modifiers present in the activity. So when Heavyweight is a modifier and I'm in a fireteam, I have to disable the heavy ammo finder perks on my armor otherwise I will not get any heavy ammo drops. Also, for the Haunted Forest, if I have a mask equipped, I have to disable the heavy ammo finder perks on my other armor or I will not get any heavy ammo drops. I've been noticing an issue for the last couple of weeks involving heavy ammo drop issues when I'm in a fireteam. Currently, I have three armor pieces with the heavy ammo finder perk. When I play solo, heavy ammo is dropping regularly all over, patrols, public events, heroic story missions, lost sectors, etc. But, when I join a fireteam, I suddenly do not have any heavy ammo dropping. I was doing a strike with a random fireteam and had no heavy ammo drop. I went in and turned off the heavy ammo finder perk right before the boss fight and got one drop. I've also had it where other members of the fireteam are getting heavy ammo dropping all over the place, but I am getting zero even though I'm the player with the heavy ammo finder perks enabled. Is anyone else experiencing this? Is this a known issue?
