After I posted the above, and after reloading the game, I verified that "On the Ropes" remained missing from my journal and that Gwydian's loot-able corpse was on the ground where he fell. Then I reloaded an earlier save and tried an exploit: I stashed my crew in the nearby basement and went up solo to beard the evil magister at the scaffold. As soon as Gwydian got loose, I ran to the edge of the platform and teleported myself down to the area near the cellar door. On the next turn, I ducked down the cellar hatch and up the ladder on the other side. I then emerged from that house and went to visit Hannag, who thanked me warmly and rewarded me with another source slot. C'est la guerre!
