Rakish Sneak Attack bugged?

[Vim]

So I made Astarion a Swashbuckler, and I'm trying to figure out if I'm doing something wrong, or if the ability is bugged.

As you can see in this picture, Astarion is using a Rapier to attack someone wielding a crossbow. I am using "Rakish Sneak Attack", but the prompt says I need advantage to use it. I thought the whole point of the swashbuckler was that you don't need advantage?

My understanding of it, allies cannot be in range neither.

You need to get behind him for advantage. Your enemy is literally looking right at you.

Oh! ... okay, yes, I have been doing this all wrong. Thank you!

You can Sneak Attack an enemy right to their face. Being behind them for it is not a thing.

Frankly, OP, you not giving the entire image of what shows on the UI is doing you a disservice as when you target an enemy with sneak attack/rakish attack it shows under the enemies HP if they are countering your attack in some way.

One of the party members appears to be relatively close to Astarion. "Rakish Audacity" only applies if no creatures other than the target are within five feet of the rogue, so check that.

Well that answers my question. Thanks everyone!
