I've done some searching around to see if this is a known issue or not and I haven't yet seen it mentioned, and if it has been, I missed it, and I apologize.

I'm having an incredibly annoying experience with ranged weapon attacks, specifically the shortbow. I noticed it was odd in my first attempted playthrough when I was a rogue. I looked it up then and people have been saying sneak attack is super bugged, so I decided to reroll and picked a ranger this time. Problem is, the issue is still happening. Every time I hit any creature with my shortbow attacks, they deal exactly either 3 or 4 damage. Thing is, 3 damage shouldn't even be possible considering my dex mod is +3 just by itself. So the damage MINIMUM is 4 from being 1d6+3. However, I roll 3s about half the time, and 4s the other half. And it isn't just my ranger either, it's also the fighter with her shortbow. Always 3 or 4 damage exactly, even when she scored a critical hit once! I tested this over 20 times, and every single ranged attack with the starting shortbows were 3 or 4 damage.

Is it just me having this problem? I legitimately couldn't find a single other mention of this outside of people complaining about how sneak attack damage works, and this issue seems unrelated.
