Missing Items/Loot Has anybody else noticed that?

Something I've discovered since the latest patch(es):

Carriers can't be bought anymore.
Vehicles drop fewer (??) as chest-loot in missions than before.
Arul Saba Gems don't drop at all anymore as loot from mobs.

Is it only me who has noticed these things???
Or have we just been extremely lucky before in our guild and now the luck turned.
I'm fine with it if it's like that - curious minds want to know however, if these things are still in the game as items to be bought/looted.
