I've just unlocked the Retriever module and it's not tracking my kills. I've killed like 20 people and the Retriever only tracked 10 or so of the kills.

Same with Detonation Delay. Dodged plenty of nades and only tracked 6 or so.

I do believe someone said at some point that retriever bonus actually only tracks kill streaks?

Also I think the detonation delay module only counts if you're close enough to the explosive when it's triggered by the opposing player.

If that doesn't help for the time being yes, they're bugged.

Who said it only tracks kill streaks? Where is that officially written..

Yea the Retriever mod does only pick up your killsteak kills or something like that. I'll have 10 kills with it in a match and go check my stats and yet it only goes up by 3-4 kills when it should count them all. It is a very useful mod but I would like to be able to level up as quick as the other mods because 2nd level is 1 less dog tag for killstreaks so a 2 streak gets you radar but at this rate it will take me over a month to level it up.

I have not invested in the grenade mod for it seems only useful in games like crash site where people know where your going to be hiding (having to break out the nades and not just hit a button to throw quickly is the main reason nades are not spammed like crazy in this game)
