It's Raining Treasure! glitched?

[wlkownz]

Hi there people,

 

I was playing some FC6 this afternoon with a friend of mine together to farm some trophies for my account (he got platinum already) and now we we're on a task to fix al supply drops for the trophy 'It's Raining Treasure!'. This trophy need to get 10 supply drops, from the icons or those that drops random in the map. I've done literally every icon we saw on my map and I intercepted some randoms (I think in total of 4), and I still haven't unlocked this trophy. I need to find some more spots in the game were I can activate a supply run, to try and get some more maybe it doesn't count right.

 

Or are here people that are familiar with a glitch in this trophy? Or is it because I did it together with two people when the game says 'Solo Campaign Only', while normally we play it together and these trophy's will still pop-up only for the party leader... Help me out, so I can figure out what to do and maybe start a second game to get this one or just try some more supply drops!
