Gnome spell cast projectile delay?

Hi, first time posting and it's probably for a petty reason, but I've noticed that with the new WoD models on 5.4.8 the gnome has this weird spell projectile delay bug, where the animations and "hand effects" (like fire for a fireball) ends, but the projectile shoots half a second or even a second later. It's been happening only on my gnome male and it's been really bothering me D:
Anybody know how to fix this? (Tried re-downloading the models various times, doesn't fix the issue)
