I have noticed a few buggy issues with the Achievements. The two that I have noticed personally is that I have not been credited with 8 man HM and SM Jarg and Sorno (have SM codex on empire toon and the HM codes on Pub toon). The other one is under Legacy > Possessions > Weapons that states to obtain the Cathar honor sword, and a specific dual edge sword and techblade. My marauder is dual wielding the Cathar honor swords presently.
Anyone know if these are know issues or is it just me?
Oh, the Cathar one has a work around (unequip the sword then log out). I had the same problem with my Containment Officer gear but just unequipped it all.
