I dunno if this is the correct place, but...
It seems I've stumbled across a bug in the original Fallout 2.
How to reproduce: join the slavers in Den, then go to New Reno. Do the first Mordino's quest, then take the second one (getting the tribute from the Corsican brothers). Now go to their studio, try to talk to the brother who's present... No luck: he just keeps saying "We're all stocked up, slaver." and "These slaves are mine, slaver. Watch those eyes.", and you
can't initiate the actual dialogue.
If you're not a slaver, everything's ok: you talk to him, tell him who sent you, get his money.
The problem is present in both vanilla unpatched Fallout 2 and F2RP 1.2.
EDIT: the fix turns out to be trivial. Open the script NCCORBRO.SSL, find the procedure "talk_p_proc", and remove the following lines from it:
Code:
end else if (has_rep_slaver) then begin
call Node008;
This will not affect the brother's timer-based float quips, only what he says when you click on him.
