"For the Greater Good" stopped working?

I'm a new player and was farming Gold/Favor in Descent Into Avernus with the Sgt. Knox + Makos strat. With Astarion, Azaka, Valentine, Jarlaxle for gold bonus piling, Ezmerelda and Minsc to make the enemies come a-swarming, and Jang Sao and BBEG being pretty and boosting Astarion's Generational Wealth made the "For the Greater Good" combo a killer...

... until it stopped working. I reached the ability cap for the characters at Gold e86, and suddenly, Makos was only firing 1 beam at a time again. I thought it was a soft cap feature, but turns out it just stopped working in general. Is there something wrong with my game or is there something oopsied server-side that I have to wait until it's fixed?
