What exactly causes one to stop after Ice Spear or Thunder (I think also Fireball) Explodes/hits? If I recall, every time I would ice spear, upon a frozen mob taking dmg from the spell, I would get desynced as I assume the server stopped me where I was standing, while the client allowed me to continue to move. The same goes for thunder striking down, and 60% sure I remember fireball exploding doing this as well.
The server stops your movement on their side when those skills land. They forgot to send a stop movement packet and therefore you get de-synced.

I could have told you that myself but attempting to look for it or perhaps any subsequent ones in the NA package data gave me back nil.
Duh. Because all gacha data is on the server side.
