I've noticed these days that sometimes skills fail without the red letters "Skill has failed." - it just casts nothing as if it's under the affect of Volcanic Ash.
Example 1:
Right when I log in my super novice, the first 1-2 casts of Warp Portal does not create a warp. No red letters are shown - just nothing happens after I choose a place (It consumes a Blue gem too.)
Example 2:
I buff myself with Blessing and Agi. When the timers are low and about to expire, I recast Agi and Blessing - animations happens, everything is successful, but the buffs are not replaced. They end very shortly after. (Blessing and Agi level are the same, and I know the skills is casted because it -15HP when I casted Agi).
It's annoying sometimes because it takes 3 blue gems to get a warp and I have to wait for buffs to expire in order to rebuff. Anyone else having these similar problems?
