Stealth Bonus Failures

[Brainwright]

Since maybe two months before Banshee Prime was introduced, the ability to keep a stealth bonus in a mission has become extremely difficult for most weapons with common builds.

The problem seems to be that targets will become aware in the fraction of a second between when a shot hits them and they die.  This means that weapons using multishot will fail to stealth-kill their target, especially if you are in front of the target when you kill them (even invisible as with Loki).  So shotguns are completely useless now, and weapons using multishot will often fail to stealth-kill an enemy.

I know this sounds like a gameplay mechanic complaint, but it is definitely buggy.  It simply does not work based on the information given to the player.
