As your guide is one short anyway I ended up missing out on the achievement and will now have to collect them all again on my 2nd playthrough. Whilst I appreciate you putting the effort in to make a guide, you should at least have mentioned this upfront instead of passing it off as a complete list!
I missed more than one on my playthrough and still got the achievement. You must have missed another one some where along the way
