There are a few errors that slipped into the first printing. They'll be fixed with the second printing, but they should be pretty straightforward to divine. Room 12 key should have East instead of West, Room 15 is referring to the upper and lower exits both to the West (this one from a last-minute map change that didn't get reflected in the text), Floor 2 Room 22 should be deleted, Floor 3 Room 12 should read West instead of East, and the Sea Thing Growth map should have a connection between 8 and 12. Also the exits from Room 6 of the Sea Thing Growth are a little unclear: North and East are referring to the connections to 11 and 12 respectively.
The ePub is fully bookmarked and easy to navigate while playing on a VTT, eg. In all honesty, I wasn't even going to release a PDF, the ePub serves every purpose better.
