Hello
My guild has recently started progressing in BWL. Today we started our first attempts on Vaelastrasz, and was about to get the killing blow, when suddenly he despawned. There were rumours before he despawned, that he would dissapear after one hour - which was exactly what happened. I believe this is a bug, since it locks the rest of the instance - and considering it's only wednesday and Molten Core is cleared, it's kinda devastating for a guild wanting to progress. Is there anything we can do, so we can keep progessing in BWL on our next raid (sunday)?
Best regards
