I did notice one thing: During the encounter on the RNS Coaltongue, various relevant terrain features are said to be marked by letters on the map - but those indicators are not present on the maps presented. It's still pretty easy to intuit where they are, however, so it's not a crippling issue. Also, the early social scene "The Crowd" prior to boarding the Coaltongue is marked as a Level 15 Social Encounter, rather than Level 1.
Other than those minor editing issues, I'm quite fond of the non-standard monster design and encounters in the adventure - and I'm very glad that there's a solution to the whole "party encounters high level NPC/possible enemy, sucks to be you!" situation that seemed to pop up every so often in WotBS.
