Multiplayer issues

I've had some issues with multiplayer the past couple days. Not sure if it's on my end or not. I would join a game, and whenever I run by an ammo box, it would automatically pick up extra thermal clips. I stand next to it for 20 seconds, and nothing happens. Similar issues, where I would hit a husk with a heavy melee ability and it wouldn't do anything for 15 seconds. Normally if there was lag, it would maybe be a 5 second delay before the husk gets hit and dies, but 15 seconds? Husk is still alive. Sounds a bit fishy. 

I was thinking it might be a hacked server, but playing multiplayer since release and this sort of thing popped up this week a few times (didn't happen before), then maybe it's not that way.
