found a few bugs (well, 2 so far) at the achievements:
1.) Grand Master Job Level it gives an OCA, but upon using it no card is given:
EDIT: as it seems, the OCA from the achievement is a different one to 'normal' OCAs from MvPs/Chests/mobs
2.) XXX Field Explanation (seems to give the same item with each achievement) the item does basically nothing: from the flavour text it might give some random amount of zeny, but it's a 0 weight etc item that is NPC-sellable for 0 zeny
more if i found bugs with higher levels....
