So you're missing a few shots in VATS big deal, why is that a problem? Also, if you are using the Gun-Fu perk, switching targets via the perk trigger does NOT trigger the bug, and shots land normally on subsequent targets after killing the first target. Likewise, if you lock onto a target, miss your first shot, then fire a second shot in VATS, the second shot will land normally. WORKAROUNDS: If you lock onto a target, then quit VATS without shooting, then lock onto the same target again, the first shot will land normally. RESULT: Your shot will miss the vast majority of the time. Don't charge your shot, just tap fire is sufficient. You want to be close to the target so you get a high hit percentage.

Use VATS to lock onto an enemy you have not previously locked onto in VATS.

This is a brand new bug, and here's how it works: The first shot against each target in VATS almost always misses.

The 'Blank Fire on Sever Load' bug that happens when you load into a fresh server and the damage from your very first shot does not register.

The 'Held Charge' bug that happens when you enter VATS, start charging when you're at something low like 5% to hit and then creep closer until you're at 95% to hit nor.

The 'Charge Up' bug that happens when you charge a Gauss shot BEFORE you enter VATS.

I've researched this, and here's what I've found. The Wastelanders update introduced a new bug that makes Gauss weapons like the Gauss rifle and the Gauss pistol consistently miss 95% hit chance shots.
