You can't have two ammo packs going at the same time

I don't know if they recently fixed this but if I drop the normal ammo pack and then use the ACE (B) option the 1st ammo pack disappears.

At least with the B key we can drop mines and drop ammo.

Have you upgraded your ammo pack to level 3? That's been known to mess up your second ammo pack placement. However, last night I was still able to place both my ammo packs.

still works for me. i havent certed into the ammo pack. i use the ace ammo pack as my primary and the utility one as a secondary.

No I have not upgraded to lvl 3. It makes no sense that the game would remove the lower pack though. Hidden Perk?

I think it still works, but since I have C4 instead of ammo pack utility, I don't know.

Working for me, and I can't remember how far into ammo packs I have certed.

Was able to put one at the top of each stairwell in a Tower last night, no problem.
