Just a heads up, I checked these forums a bit for this prior to making the thread and could not find one. My apologies if this is a repost.
As I was doing Malgrave challenges till my eyes bled, I noticed something interesting. After completing a challenge and receiving my Satchel of Scavenged Supplies, I only had 1 inventory slot open. When I tried to open the Satchel, I received the "Your inventory is full" message. After clicking the bag and receiving the error 3 more times, the 4th try actually opened the bag and gave me loot.
What does this mean? This means that loot from opening bags is determined when you actually open the bag, and not when you obtain it. It generates a new loot pool each time you click the item to open it, then checks to see if you have enough inventory slots to actually receive that loot. If you cannot, it then cancels out the action and does nothing.
How the **** does that help me? Well, I'm still trying to discover ideas, but I have a theory (seems to be working so far).
Most of the time when opening these bags, you receive 4 consumables (basically garbage). When you do receive an AMP, usually it comes with 1 other item (sometimes this is not true). When opening my bags, I will fill my inventory till there is 1 slot remaining, then open it. This gives me a higher chance to actually receive AMP's and not the crappy consumable spam. So far it seems to be holding true, but I haven't tested it on a large enough quantity of bags to really see if it helps enough. I'm running through the numbers now and recording all my openings prior to using this and after.
Please comment to let me know if this is retarded or if you can help improve upon it!
