Made an account just to post this. About 100 hours into the game other than a few crashes here and there it's been fine. Recently after reaching the Prydwen and completing some main story BOS missions enemies started being invincible at random. At first it was just one group of super mutants I ran and fast travelled away. Around 3 hours later a Deathclaw becomes immune to all forms of ranged damage, I reloaded a save and killed it. Now though every single enemy encountered is invincible to all forms of ranged damage minus critical shots. Companions and other NPCs can damage each other but the Sole survivor cannot do any ranged damage to NPCs They all have the same theme in common where if you zoom in during vats the screen shifts away from what you're targeting then realigns itself on the target. Enemies can be killed with either melee or critical shots and enemies that are killed by either method ragdoll in the air and "float" backwards for a few seconds before falling. There are multiple videos showcasing this game breaking glitch and there are even cases where it occurs during main quest lines, in which case it completely breaks quest progression. I'm a patient person so rather than complain I decided to revert a save file 2 physical days old. Now my issue and the reason I'm here is that enemies which I cleared 2 physical days ago are now also experiencing this bug en masse. Now my options are either quit this game which i spent 70$, make a new character and hope the game is no longer broken and lose 100+hours or change my character into melee only. This has been a frustrating day trying to bypass this bug, please resolve this issue as soon as possible.

Edit: Is this some kind of DRM thing? I switched to online and everything is working normal now. I remember reading some games made the game really annoying to play when people would pirate it and play offline to avoid being caught.
