I am finally getting around to doing my Death Guard in Warhammer 40k. In the Dark Imperium, the Lord of Contagion, was listed at 137 points, in the Codex it is listed at 120 points, but in Chapter Approved it is 100 points.
There are no corresponding errata for Dark Imperium and the Codex for adjusting the points. Now, chapter approved is after Dark Imperium of course, and I assume that it is also after the Codex, so should the point value listed in chapter approved be used?
This would apply to more than just the Lord of Contagion of course. And, how would you determine when chapter approved supersedes the codex; eg. the Tau codex (which came out after chapter approved)?
Following that, how would someone find out chapter approved changes if there is none listed for the specific codex, without purchasing the book? Seems rather schmuckish for GW to expect you to ALWAYS purchase chapter approved for updated points and rules
