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

So I guess I've been affected by this, too?

I have twelve inert stones in my inventory, two regular bloodstones, and a bloodstone shard from the wounded mage quest. All of the portals except the one to the Forbidden Zone are now open, I've beaten back the fireballs attack, etc. When I activate any of the remaining three bloodstones, they give me XP, heal me and everything that goes with it, but I don't get the normal indication that a new portal was unlocked in the homestead (the teleporter symbol on the right is supposed to glow green), and indeed Zixzax doesn't react when I return. This happens regardless whether I am activating the bloodstones in the Homestead or elsewhere.

Any ideas?

EDIT: Isn't it weird that I have 12 inert stones but only 11 open portals?

EDIT2: Decided to return to the Source Temple and the door suddenly opened. The Forbidden Zone is still inaccessible from the Homestead, however. :-/
