Achievement Bug

Like the title says, some hidden achievements are not working, the achievements are:
Full-Time Job - which needs to stay online for 6 hours straight, I tried several times with 6~8 hours straight each time and didn't get the achievement.
A Little Ten-der - which the player needs to die 10 times, I've tried dying more than 30 times and didn't get the achievement.

Also crystals aren't breaking upon death (without crystal binds)
My character died more than 30 times and not a single crystal broke.
I managed to get the achievement Ideal Crystals (which you get by dying 30 times without breaking a crystal) because of that, but can't get the Imperfect Crystals achievement (which you get by breaking crystals 30 times upon death).

Btw. did you have active club? There is a permanent crystalbind included.

Nope.
I did a few more testings, the accessories crystals breaks when dying, but weapon and armor doesn't.

Quote from Navi

What level and gear did you try this?
For the higher weapon and armor (exodor and higher) we added the crystal slots later, maybe that's what caused this problem.

I was testing using level 50~58 gears at the time.
