Reloading Grenade Launcher.

[Enigmatic]

I can check the ammo. The Chambers look full. But can't reload the Flash Grenade launcher.
I had a second drum.

If you mean the Tactical (5 key), it should work.

If you mean the flash launcher primary... I've heard this doesn't reload properly, but I haven't tried it myself. Hopefully someone more knowledgeable comes along.

it been like that since they add AP and HP. I sus it because the game stats saying these flash round are AP like they dont proper make rounds for them yet
