Mass Effect 2 No Ammo Drops In Loyalty Side Missions and Some DLC Content

I had an opposite problem with my Infiltrator playing on PC. Loyalty missions were the only ones that had enough ammo drops, during most of other missions ammo drops were so scarce that had to rely on powers and squadmates (and hide in the meantime). Many times moved from one location with enemies to another with no ammo at all and frantically searched for even one ammo drop under tactical cloak. I guess it is alright for Insane difficulty (the name says it all))) but just a bit too much for Veteran.
