I've only recently started going for the luminary tools and I've noticed that the achievements for those items are asking for set numbers of items to by synthed when what it actually wants is for you to do a set number of synths.

For example, say you were doing the achievement Pounding Out the Dents: Apprentice. This achievement asks for you to "Craft 750 items requiring level 21-30 amorcraft recipes." If you used a recipe in that level range that made 12 items each synth (like 3 iron nuggets into 12 iron squares in a single synth), it should only take 63 synths to get from 0 to over 750 items and unlock the achievement. However, the number only goes up by 1 (thus, the number of synths, not the number of items) regardless of how many items the synth makes.

Steps:
Open the achievements menu, navigate to the synthesis submenu, look at the requirements of all non luminary achievements in there. They all say "Craft [#] items [etc]". Find one that you've not yet completed. Click on it to expand how many of those recipes you've actually done. Synth something that makes multiple items at once. Check the new number of how many items you've supposed made and compare it to the previous number. Notice that it's only gone up by one.

Possible solutions:
Either change the wording to ask for that number of synths or make it actually count the numbers of the items made. The first solution is fairer to those who've already pushed through so much hard work and don't want to see this handed to those who came after, but the 2nd is so much more convenient to those of us who came after XD
