About Sirius

I died to Sirius right after he descended. But when I returned, it had been 30 minutes since Chaos's domes had moved, and there was no way to reach him. I don't know if this is an old issue that wasn't fixed in the Sirius boss, or if it's just meant to be that way and the player has given up on attacking him.
