I tried to get my Blessed Minekeep's Pickaxe today, but there are only 153 total items out of the required 160 in my mining log (both sides, including all folklore books). I doublechecked by working on Botany to make sure that maybe it wasn't just a case of the achievements being added with future content in mind, but there are 234 items out of the required 230 in my botany gathering log... so that one is obtainable. It appears, then, that the mining requirement was erroneously set too high and should probably be 150.
