Level 50 Dual Blade Coupon Skill Point Issues

I don't think the coupon has anything to do with it?

My main DB came from the level 50 coupon as well and I have never had any SP issues. A secondary DB I have access to is since its release and still no SP issue. My friend has had his DB since pre-Big Bang and after some odd SC many patches ago, he started having SP issues (and now his issue is that he can't job advance to 4th if I remember correctly).

I assumed this problem was just bad luck to whoever it hit.

Did your friend's issue ever get resolved?
