Omega Mephisto disappeared

[Myself]

Me and tragos just killed all the other Omega bosses and we were about to kill Omega Mephisto when all of a sudden he disappeared from the scene. We looked around for about 10 minutes but no hope. Is there a way we can get the Blue Worldstone Crystal or what's going on?

Here are some screenshots:

thanks for the reply Game i am just wondering what we could do next? cause if you give us just the blue stone that is missing how are we gonna combine them if we are not in the corrrect place? where all the omega bosses portals are...? or is there any possibility to join our game and try to open for us the portal with the omega bosses after baal dies...? sorry for bad english.
