Spell casting bug

[MethodSZ]

I'm sure by now everyone knows what i mean by the spell casting bug, but since i didnt see any topics on it, i figured i'd create one

To clarify, its when you cast a spell, the spell acts like it goes off but it actually doesnt, but all your icons remained greyed out and it acts as if your casting indefinitely until you zone

only thing i can add to this is just a simple observation i made: When casting a spell, you can immediately tell if its going to be bugged or not, by whether or not it makes a sound

When i cast a spell, and i hear the spell casting sound, i know it'll work

When i start casting, and its not making any sound, i know that it wont work and it will bug me until i zone.

Also when you know its bugged, even before it finishes casting, it wont let you duck out and cancel the spell.

So maybe it has something to do with the sound files? - dont know, just posting what i saw. thanks!

edit: only exception to this is healing spells which ALWAYS bug no matter what
