Mass Effect: Deception Mistakes Anger Fans

Unfortunately, I don't have the time to follow a single video game series to the point that I read through all of the novel tie-ins, but I have a special appreciation for those people who do. And it's those fans who are now up in arms over dozens of lore, timeline, technology, and character mistakes that have been found in the most recent Mass Effect novel, Deception. Some big ones in here:
2. There is a batarian embassy in the Citadel - Batarians closed their embassy in after the Citadel Council sided with humans regarding border dispute, and there was no mention of such an embassy in the previous book. [Error: Lore]

...

5. Kai Leng kills a krogan by slicing into the back of its neck and severing the spine - Krogan biology doesn't work that way - 1) there is a large hump that makes access to the rear of the neck difficult, 2) most blades (save for a molecular blade) can't penetrate the thick hide covering the rear of the neck, 3) even if the spine was severed, the krogan still wouldn't die; instead of a human-like nervous system, it has a 2nd circulatory system with an electrically conductive fluid. [Error: Lore]

...

25. Anderson thinking that the Citadel trap had been sprung (so successfully) they were still reparing damage - The entire point of the first game was that you prevented that particular Reaper plan from succeeding. And the damage to the Citadel mostly resulted from Sovereign exploding. [Error: Lore]

...

14. It is stated that it is (impossible to see anything) in FTL - This is untrue. To quote the Codex: (As the subjective speed of light is raised within the field, objects outside will appear to red-shift, eventually becoming visible only to radio telescope antennae. High-energy electromagnetic sources normally hidden to the eye become visible in the high blue spectrum. As the speed of light continues to be raised, x-ray, gamma ray, and eventually cosmic ray sources become visible. Stars will be replaced by pulsars, the accretion discs of black holes, quasars, and gamma ray bursts.)
Thanks, Kotaku, where they also point out that some fans are even burning their copies of the book.
