I'm Stuck In "fate Of The Fallen"

It went rigth until the part wehne I need to throw the "Molten Cores" into an hopper in this underground. So I threw 3 Cores at the time. "The bridge has been fixed" the chat said. I crossed the bridge but nothing happend.
I did that once more but still nothing, so I watched a walkthrough and saw that there should had happend something. So I used /kill because I haven't got any teleport scrolls. Now the portal to the "Time Travel place" isn't next to the "mage"... What shall I do? Please help me

 

Get another Theorick's Wand, the mage will then summon the portal again I think. Otherwise just walk to Time Valley (with a Theorick's Wand), and throw it into the hopper again, etc. etc.

 

Thank you! It worked.
