Forbidden Secrets Of The Undisputed Claim Bug

[Elmerfudge]

I can't progress this quest. Im on PS5 and the game has the latest patch installed! To continues the Faction Quest "An Equitable Arrangement" I have to complete the Side Quest as mentioned in the title. To do this I have to interrogate the Man in the Moon Mask. After I start the dialogue I have two options. The standard and a Professor option. No matter what I choose the next dialogue options are the standard one and one that needs 9 observation. What I don't have. After being forced to choose the first option I get another dialogue option. The standart one, a professor option and a Science 9 one. I dont have 9 science. So stuck with either of the other two options. But no matter what combination I choose or companions I bring along. I am left with the "Think I will slink away option." In other words I cannot progress this side quest or the Faction quest that's tied into this one. According to the patch notes, this quest was patched. But it seems it not. Am I missing something or am I screwed? Not having enough points in specific skills should not force you out of a side or faction quest!
