When you're at the basement, under the dish platform, the AMS will shoot down missiles above the ceiling. Considering the volume of fire at the center, this is both a bug and an exploit. I was with a RFL and noticed his AMS firing like crazy seconds before the computer informed me of low AMS ammo and I hadn't even seen an enemy 'mech yet.
Guess it's the same bug that allows laser shots to go through walls and you see them as streaky lines in the air on maps like this, all the time.
