Hello everybody, here is my experience regarding Sneak Attack.

My understanding of when using the Sneak Attack ability should trigger a second damage roll (correct me if I'm wrong)
- Whenever you see any green arrow(s) next to the hit percentage, without any red arrows, and you use one of the Sneak Attack abilities
- If you don't see any green/red arrows next to the hit percentage, but one of your allies is standing next to the enemy, and you use one of the Sneak Attack abilities

What works for me:
- Most of the advantages work for me (backstab, high ground..).
- Having no advantages or disadvantages, but having an ally stand next to the enemy.

What doesn't work for me:
- Having an advantage called "Advantage on attack" and using one of the Sneak Attack abilities does not seem to trigger the extra damage roll.

I also tried having only the "Advantage on attack" advantage AND having an ally next to the enemy, just to check if this advantage "cancels" any sneak attacks, but no, it does work.

So I'm assuming the game just ignores "Advantage on attack" as being an advantage when using a Sneak Attack.

I hope this will be fixed soon.
