Payday 2: Little Friend 7.62 Assault Rifle Bug. HD

Skip to 0:45 for the bug in action. If you go down with the Grenade Launcher active, are picked back up, then you swap to normal "Firing mode", your weapon will retain the animations from the Grenade Launcher mode. This can be remedied by swapping back and fourth again, but it can still be quite annoying.
