@ No, the story actually does have flaws, and one major flaw is the existence of Ymir within the Survey Corps gone unnoticed. That's a flaw, because Hange and Erwin (and most likely, all veterans) were aware of the content's of Ilse's notebook, and how could they not notice one of their recruits was named "Ymir"? (Not that a lot of trainees joined the Survey Corps). There are many other flaws, but I can't think any other right now.

@Anon Hange's theory isn't flawed as far as I know. We know that Ymir stole the power of Titans from BRA's people long before the story begins (she says so in Chapter 48). And then, the same year Wall Maria fell after the first attack, she was able to regain her human form, and as far as we know now, was because she ate Marcel (and killed him), and this is what gave her her Titan-shifting. We know this, because she says so in Chapters 46 and 47. Ymir clearly was hiding from BRA, because she knew she did something which is considered a crime, but we don't know if she refers to either stealing the "power of Titans" or killing Marcel. I don't see how Hange's theory flawed? As far as we know, the theory confirms what we already suspected about ability-transfers (remember that the "Ymir ate Marcel and acquired Titan-shifting" was long considered until this point). The only thing we can't know until Crunchy's version (or the japanese raws) are out is if Hange really thinks Reiss is going to eat Eren. We cannot really trust a fan translation, specially if it is Japanese -> Chinese -> English.
