Boss fights textures not loading

I had 2 boss encounter. Sirus and Atziri both normal. With Sirus the wall won't load at all where you need to get out so the giant rock doesn't hit. I died to this multiple times and couldn't complete the fight. As for atziri it seems something is wrong with this fight. Some attack I'm not able to see which is killing me and I feel like it's her big aoe which is the only attack I'm not able to see in the fight. Also is atziri always invisible? I have checked a few youtube videos of the fight and it doesn't seem to be the case.

When are you guys releasing the patch for these issues? I have been playing through these issues hoping there would be a patch by now but it's been a few days now.
