Playing the last version.
Before activating the last quest I uncovered the protectorate spy by talking to Darling and get the word "Muffin", I go to the Hanging Rat and talk to Marcella, I kill Alvin Bate and begin the quest, but for some reason the reinforcements appears and when debriefing with Trenton he says we don't have discovered the spy yet and in the dialog the NPC picture disappears and the name changes to "Unknown", also Trenton speaks like if Alvin were still alive.
IIRC correctly twice were the chances I have uncovered the spy using pickpocket and persuasion before triggering the last quest and get no reinforcements, it doesn't work by getting the info by Darling?
