I think I got 26 or 27 on my first one. Made a point not to miss the side quest I flubbed the first time on the last one and hit 28 right before the final boss.

I got the lore achievement my first time through. I'm guessing that there are exactly 60 pieces of lore and if you miss one, then you're SOL. I say this because I got the Loremaster deed the first time but not the second. FWIW, it does seem that a few of the achievements are either bugged or broken:
