Some severe weirdness with RC5. WP rifle grenade works, but clicking to reload after firing appear to dump the magazine from the rifle into inventory and replace it with Glaser ammo (when using a HK416 14") instead of loading the next rifle grenade. This might be connected to the Masterkey reloading issues you were having.

Detonating an M74 pack in inventory results in a small non-damaging detonation, a pause, and then a deadly smoke cloud. No fire, but that may be intended. Lighting also seemed to work.

Also, I've got a small list of item problems. The SMG Leg Rig doesn't have a BR name. The Bomb Pouch is listed as not for sale in BR.

The Radio Set still has a Warhammer 40k BR description (base 1.13 issue, I think).

And the AA-12 shotgun is still colored oddly.

Edit: Also, is the ALICE backpack meant to be unbuyable?
