Larian Studios Forums Baldur's Gate III Baldur's Gate III - Suggestions & Feedback Tasha's Hideous Laughter bug?

I was fighting the Duergar at the docks for the Myconids. I cast Tasha's Hideous Laughter on Novice Garmor and succeeded. The conditions he had on him were, Enlarged / Hideous Laughter / Threatened. When hovering over Hideous Laughter it says "All attacks made withing 10ft of the creature have Advantage against it."

Using Astarion, I tried to backstab him. However, it would not let me and had the red text saying "You must have Advantage to use this ability".

Am I missing something here or is this just bugged?

Advantage can get cancelled out by disadvantage

Looking at the screen shot I took, it didn't say that I had disadvantage. For example, like how it tells you that you have disadvantage due to the target being obscured.

Yeah, this is a bug that's been brought up before. Prone does not currently give rogues advantage for sneak attacks when it should. Hideous laughter forces enemies prone. It does still proc an immediate critical hit when the effected target is hit in melee range. If you want to use sneak attack though you need to acquire advantage on the target through another means until it's fixed.
