Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - Technical Issues Game Breaking Bug: Zixzax not opening portals

I am having the same problem. End of Time is under attack. I am sitting at level 20 with 7 inert stones, 4 blood stones. I only have the Inner Chamber, Hall of Heroes, and one element cellar open. I've tried killing Zixzax and this didn't help. Has anyone figured this out?
