Tolstoy's bloopers

Is it sacrilege to pick apart War and Peace — "the greatest novel ever written" — on this most superficial of levels?

It started innocently enough: the copyeditor in me notes a discrepancy and dismisses it as a typo. The next point I notice is not something wrong, exactly, but a disconnect between specific words and my sense of events in time — perhaps something unintended was introduced in the translation. But the more it goes, the more I believe Tolstoy had a very poor sense of time; at least he didn't map out a timeline for his characters.

Here are the discrepancies I've found:

1. Anna Pavlovna holds a soirée some July evening, 1805; Pierre leaves the party, visits with Andrei, and steps out into the June night. Typo?

2. Lisa goes into labour March 19, 1806. That previous July evening, we're told she "being pregnant, no longer attended any of the gala evenings," as though it had been going on for some time. How long had she even known she was pregnant? — "soon to become a mother," "bore her burden," "waddling steps"; she's plump and stout even in these early days. Were these references to her condition translated with some exaggeration?

3. Later in the summer of 1805, the Rostovs have a party for Natalya's name day (August 26). Natasha we're told is 13. (Sonya is 15.) When her brother returns in early 1806, she is "smiling as only a happy girl of fifteen can smile" (Sonya is now 16). (Later in 1809 Natasha is 16.)

4. Early in 1806, Rostov returns home on leave. (He'd left sometime after Aug 26.) Twice it's mentioned he'd been away for a year and half. (These bits are intercut with other scenes definitely occurring in 1806.)

5. In November 1805 the deal of Pierre's marriage is sealed, and he's married 6 weeks later. March 3 he's at dinner at the Rostovs and calls Dolokhov out to a duel. Dolokhov's mother: "And if he was so jealous, well, as I see things, then he ought to have shown it sooner, instead of letting it go on for a year."

6. It's the third day of Christmas holidays; Nikolai and Denisov plan to rejoin their regiments after Epiphany (January 6 by our calendar). There's dinner, a ball, a couple days go by, gambling, Denisov leaves, Rostov stays on a couple weeks, then leaves at the end of November.

Of course, none of this diminishes the quality of the work as a whole. Although, in a lesser novel, I might find these discrepancies distracting, evidence of a sloppy mind even, reason to (gasp!) abandon a book (or at least scoff at it).

I believe W&P was published in instalments, which likely accounts for most of these oversights (any insight into 19th-century Russian publishing practices?), but I'm curious whether any of these might be the effects of sloppy translation (are they present in your editions?). Most importantly, I want to know: have you come across any other "bloopers"?
