So, I beated the storyline, and sow that I can't buy the Sticky Bombs from Armando no more, luckily I can replay Bang Bang to get free... But still...
I always used to buy Sticky Bombs from 'Mando, now they are gone!! In videos I see it's above the Rocket Launcher,
but I don't have it no more... WTF?
I am using PC, unmodded, Legitimate, EFLC version.
Also, an I the only one to notice that there is a gun, possibly Combat Pistol missing in Armandos Gun Van as well?

This glitch is because you replayed the mission Bang Bang and failed it. The only way to fix it is to replay Bang Bang and COMPLETE IT. I have had it happen to me many times before.

Holy sh*t, you are right, it worked!
Thank you!
