As threatened, here's my typos list. I'm sure there's stuff I missed too, but hopefully I got the majority of it:
Pg 11: "These vessels may purchase one of the following upgrades at the paints cost listed:" should be "points"
Pg 16: I don't recall, was there supposed to be some minor bit of text limiting the number of variant Murders in a fleet list? No more than half of the Murders fielded due to relative rarity, or something like that? Or did we choose not to bother with that restriction?
Pg 17: Slaughter-Class Cruiser has Prow Batteries str 6 30cm Front arc and Prow weapons batteries st4 8 30cm left ("port") arc. Should be strength 8 30cm Port Batteries.
Pg 30: Only realized this now, but the image for the Scion of Prospero depicts weapons batteries and lance turrets, but the rules only list weapons batteries in the loadout. Are we taking the "Slaughter" approach to gunnery (which is totally fine by me)?
Pg 33: "Ships with the Mark of Khornehave double their boarding value." Needs a space, alternatively, the "have" is unnecessary anyhow.
Pg 33: Under Chaos Ordnance, the first time Doomfire Bombers are mentioned, they're typo'd "Doomjire."
Pg 40: Chaos Strike Cruisers. I would suggest a re-wording of this paragraph: "If the Warmaster's ship is given a Chaos Space Marine crew, it is assumed that he too is a Chaos Space Marine. As such, the fleet may include 1 Chaos Strike Cruiser for every full 500 points, and may take 0-1 Chaos Battle Barge total. Chaos Strike Cruisers and Chaos Battle Barges follow the rules and upgrade options for their Imperial counterparts, except that they are crewed by Chaos Space Marines, and may take Marks of Chaos."
The last bit about being able to take Marks of Chaos is my extrapolation from the fact that they're crewed with Chaos Space Marines.
ALSO, here's a BIG QUESTION: should the 0-1 Battle Barge be limited to "Standard" Battle Barges, or should we just blow the doors wide open and permit the Seditio Opprimere and Venerable BBs? I kinda like the idea of being able to use that to backdoor in an Emperor-class BB with Thunderhawk Gunships and a CSM crew. (A) The thing certainly won't come cheap, and (B) in the lore, that ship class has been around since the Dark Age of Technology anyhow, and (C) it would generally be a decent way to demonstrate the wide variety of ships available to the Great Crusade fleets and what might still be kicking around in a Legion's arsenal (or what might have been captured and repurposed since). Dunno how comfortable other people might be with the option to "give Chaos ALL THE THINGS" though...
