Larian Studios Forums Baldur's Gate III Baldur's Gate III - Technical & Gameplay Problems See invisible spell not working ?

I went into the counting house, we defeated all the Bhaalists except the 4 that turn themselves invisible after each attack.
I have see invisibility active from spell on my PC and from scroll on Karlach. Minthara is casting dancing lights, and the remaining bankers are detecting presence, but no invisible Bhaalist shows up. My party can do nothing, but let itself be attacked and HOPE that a reaction will do some damage to the attacker.
When I click on the icon of one of the bhaalists to "examine" it, it shows status "revealed", so the invisibility should have been broken. But he doesn't show on the map anywhere.
So it was a long fight, my party doing nothing and waiting for the 4 to attack and get a reaction blow. Only helping and healing our own fallen in the mean time. Only 1 banker survived.

Tav has the "See Invisibility" buff from Volo's Ersatz Eye. I noticed that many of the invisible NPCs weren't showing up. My suspicion is that the enemies were using stealth in addition to invisibility, making it more difficult to reveal them. Some Area of Effect spells, grenades, and Cleaves without targets worked well to reveal the hidden assailants. The guards were also revealing some of the invisible NPCs, though not often. The fight can be frustrating, especially since they seem to pop up all over the map.

It's the 3rd time I did the countinghouse battle. I never had this situation where the 4 invisible ones never showed up for turns in a row. And the "revealed" status shown in the "examine" window seemed to indicate something was not working properly. (You can still examine an invisible enemy by right clicking on his combat icon on the top of the screen)
I'm not much in favor of throwing AoE attacks blindly in a room, but I guess next time I'll have no other choice, because this fight was really atrocious and not much fun at all. (I'm running on balanced level)
