Thanks to SpOOky for putting together a list of questions that I then sent to my contact. They have come back with the following answers.
http://www.slaveshipsearch.com is an official game website
2. Sunda Trench
When the Sunda trench website was 1st put on Sams Laptop shortly after parts (Including pictures and text) of the webpage were removed. This was a part of the game and not just a mistake being corrected.
Hurley's entry in the manifest at first said he won $156 Million then it was changed to $150 Million also the look of the manifest was changed
This change was game related, not due to Error correction
IT SAYS MORE THAN 150 MILLION, NOT 150 MILLION EXACTLY. SAME THING, NO?
4. Chapter 2 Clue
The chapter 2 clue was changed to from "Cheyenne" to "Cheyne" This was because of a spelling mistake
5. Compass dials such as on the Maxwell-Group website Logo were edited to change the compass bearings
