Skills not working anymore

Hi prj365 here I've notice that some of my skills that's where working fine a few days ago isn't working now. I'm currently playing as a IL Mage/Battle Mage and Mana Shield, Advance Dark Aura and Advance Blue Aura isn't doing anything anymore. My IGN is Valdin.

I know, same thing has been happening to my combo attack skill, so now i do 2x less damge which is bs.

Glad someone else noticed it too. Can we get some Dev assistance here?

I play as a bishop and my magic guard and summons dont work D:
plus some of my other characters cant do damage to the monsters so its like glitched

Its been a couple of days since I started this thread and still nothing has been done about the skills and no word from a dev or even just a mod to indicate that the problem is being worked on. Could we get a little confirmation that this problem is being handled, also could others post if they are having the problem as well to determine if it's everyone or just a minority plz? thanks.
