Burst Fire Weapons' Burst Fire Gets Interrupted By Knockdown

[AureusVulpes]

So I was using my Kraken today while doing my Vor runs for Seer, when I get knocked down by a Shield Lancer mid-fire, and I notice I'm now at an odd ammo count. No magazine mods added, mag was full to begin with, so the only explanations are he somehow he hit me so hard my Kraken malfunctioned, or burst fire weapons' bursts get interrupted by knockdown. Which, mechanically speaking, shouldn't happen unless there's a jam in the gun. So I will post this here and see what others think.
