ive done it in lfr, but its only shows me 5/6( http://us.battle.net/wow/en/character/emerald-dream/Aystar/simple ), I've killed the stone guard 3 or 4 times. and i have the achievement, I know its nothing big, just my ocd kicking in ^.^
Yeah having the same exact issue here, I have killed it 3 times (3rd kill being today) and it is showing all the other bosses except for Stone Guard.
Same here. It shows that I have not killed the Stone Guard, but I have killed it 3 times in LFR
Same bug here. 3-4 Mogushan kills, but Stone Guard aren't showing up on the armory page, LFR listed as 5/6 complete. I do have the achievement for the kill, tho. It's only missing in the armory display.
