Hi, i'm a "new" player

When use the dark knight, since 07/22 patch the visual effect of skills (awakened form expecially) result broken. After 20 mins of gameplay, simply disappear. You can fix it?

REDIT: Not only dark knight efx disappear when use awk... ALL the effect of the game desappear, include AOE nob attack and opposite animation skill. The game now is unplayable.
