The tongs/calipers on one of the tables in Evelyn's hideout are showing up without a description (along with whatever the lockpicklike items are supposed to be). There are also sextants present as loot, but their inventory graphic looks like a jumble of metal lumps.
Undead archers tend to shout "You'll pay for that!" when you hit undead mages, but not when you hit anyone else (including the archers themselves).
After dealing with Evelyn's hideout and talking to Jake, the healer Thelyron will still give his "Far be it from her to tell me what she's doing..." line before continuing to the "So she was the culprit..." one. He'll still be willing to hypothesize about where she has run off to as well.
Not strictly a bug, but I find it a bit odd that incriminating items like Evelyn's journal and some of the notes in her house and the cave don't function as proof of what you're saying about her and the events in the cave, especially when talking to Aureus.
After rescuing the hapless farmers from Arhu's machine, they run off to get patched up but seem to disappear, and they certainly don't appear to set the story straight about what the Five were up to. (Everyone in town still talks about how the Five saved the town from blah blah blah...)
