So I pick up the star stone buried in the Source Temple (Yes the one with Zandalor). After I pick it up, my waypoint lights up. I go to the end of time, and all of a sudden, Zixzax is going crazy bringing me from new portal to new portal. When I saw the henchmen for hire at level 1, I knew this was supposed to happen 1 star-stone by starstone. But it happened after I had collected practically all of them. It ended at the chapel waypoint. I missed out on so much story along the way. I was 90 hours in to the game. It felt so weird hearing about the "Guardian" stuff ALL AT ONCE. Anyways, I ended up finishing the game 5 hours later. I'm just sad I didn't get fed the cool "Guardian" story along the way.
TL:DR
End of Time portals didn't open until I had collected all of the star stones.
PS: I had been back to the end of time many times after collecting the first few stones, Zixzax had no clue, and there was nothing remotely hinting at the fact I had activated the stones.
I consider this a pretty serious bug, anyone else experienced this?
