Ran into this weird bug today while playing on the highest difficulty level. When I pulled out my trusty SCAR, it said 'Ammo Low' (and I was all like WHAT I NEVER LET MY AMMO GET LOW), but there were infinity symbols on both of the ammo numbers (you know, the one on the left is how many bullets are left in your clip, the one on the right is how much other ammo you have). First I was all like SWEET THIS IS AN AWESOME GLITCH and then I tried to fire it and got that annoying little click. I switched it out for another SCAR, thinking that particular one was bugged, but I was also out of ammo on the new one too. Completely. (Which just doesn't happen.) Tried restocking my ammo at the nearest standard ammo box, and it gave me ONE WHOLE BULLET. So I just said 'F*** it' and switched it out for a Scarab. Same exact problem. Switched to a Jackal and everything was normal again. Later on, in another level of the same playthrough, I tried to pick up the SCAR again with the same results. And the Scarab. :'( Has anyone else encountered this issue? I'm making do with the Grendel but I really miss my silenced assault rifles/sniper rifles/tap-them-on-the-butt-and-freak-the-CELL-idiots-out rifles. And I don't want to just start the level over from the Campaign menu because I'm carrying a Typhoon and those are a bit hard to find.

TL;DR: I can't get any ammo for the SCAR or the Scarab. I am decidedly unhappy.

:D
