WotLK A question about Valithria Dreamwalker

[Landriazz]

Hello there,

Yesterday, we have done Valithria and we've seen something very strange : during the fight, some adds suddenly speed up and catch us in like 1 sec. We have never seen such script anywhere else and i didn't find anything in the guide i' read on the net, nore in the bugtracker.
This happened in hc and in normal (we completed the event of Valithria in normal, where the adds cannot One shot the dps and healer).
So, if anybody can explain me what happened (if it's in the retail script), and eventually what you guys do to prevent this, it would be nice for our guild.

ty for reading, and sorry for my english.

It's not only you and it doesn't relate only to VDW but other bosses as well (ie Halion, LK). This is a huge bug that has to be hotfixed as it makes some fights undoable. From a player perspective you can't do anything, basically, other than be lucky enough for the encounter to glitch in a way that you'd be able to complete it.
