Spell 91847 Bugs Out

[Alethalen]

This spell is required to have the goblin teleported to Shipwreck Shore in the Lost Isles,
Its also the only quest i cant seem to fix due to an incorrectly scripted spell??
This also prevents the entire race being playable without gm commands,
It WILL activate cinematics, but once returning it wont load the world correctly,
ONLY way to resolve the issue is to tele out of Kezan and tele back in to Kezan.

This bugs the world to an un-viewable state and will not teleport player out of the area.

Current behaviour:
Bugs Out only shows black screen - minimap and actionbars can still move around and see speechbubbles.. does not teleport u to next area

Expected behaviour:

Teleport to Shipwreck Shore in The Lost Isles

Steps to reproduce the problem:

1. Removed Spell from Database, seems to let you complete quest without bugging graphics, however no cinematics and no teleport still.

Branch(es):

Somehow I'm not sure - it's possible that this is the magic : SPELL 91847 - in patch 4.0.3 or SPELL 91847 - Added in World of Warcraft: Cataclysm. Always up to date with the latest patch (7.3.5) ?

it seems to me, although it is possible to find different information about it
