I'm stuck in Anephas Temple. I was at Kerahs once, and came back downt into the temple - Now I've learned, that I need the obelisk at Kerah's portal but:

I cant get back up to Kerah, cuz the stone pillar is always up and not coming back down so I can use it as an elevator.

I removed the figurine and placed it on the altar again - didnt help. I left the shrine and came back in - didnt help either - what do I need to do, to lower the pillar
again??

Don't you have a savegame BEFORE you visited Kerah? As far as I know that's the only possibility.
Good luck, Junglegirl

I had the same problem with the Leprechaun quest. Just download the patch to fix it.
