Every time I return a supply truck to an outpost, I have 0 Grenades and Molotovs left. Although the message says my inventory was refilled!!!
Then, afterwards, the first time I go to a shop to refill my inventory, the grenade/molotov counter says 0/3, although I have fully upgraded my throwables-pouch to a capacity of 15. Once I buy a grenade, the counter shows a correct 1/15 again.
(on PC)
Confirmed and persisting.
Once you deliver the truck the message that tells you what you are getting and how much money clearly says X grenades and X molotovs and yet they dissapier instantly, they are gone. Not only that but the shop is messed up as well. It show that you have 0 out of 3 grenades but once you purchase one grenade the value of possible grenades that may be purchased will fix it self so you will then see 1 out of 15 (depending how throwables upgrades did you make). Same with molotovs.
This bug is confirmed on Win 7 patch 1.4.0
Also if you destroyed supply truck on territory of enemy's outpost and then took control over that outpost, it's posible to get delivery bonus from already destroyed truck.
Proof (sorry for rus localisation, but icons in left upper corner can give you some idea of what's happening): http://www.youtube.com/watch?v=PSUlS...A1acEumiAznXkQ
So, it's possible get both bonuses from one truck.
