Titan's Grotto, Zalmarath, the Colossus bugging on PS5

PS5

So i went to fight it and i died. Boss continued to act 1-2mins while i was dead and then i got disconnect. Boss had around 10% hp left.

Second attempt game automatically went to PAUSE and couldnt remove it and after a while game disconnected. Boss had around 10% hp left.

Third time i also disconnected. Boss had around 10% hp left.

After that i disconnect every time i start fighting boss.

Also once when using Electrocuting Arrow i fell through floor but came back after skill was done

I'm also having issues with Zalmarath:

Boss becomes impervious during the fight, seemingly at random. My attacks just pass through him and he cannot be damaged at all, until I reset the fight.

I fall through the floor in the arena. Seems to happen when I roll near the edge and/or when he does his arm sweep attack.

These have all been issues since at least 0.1.

Also this is a design issue, but none of this boss's attacks can be parried. Not even the adds in the second half (the cold explosion spinning robots) can be parried. So there's no way to build up frenzy charges as huntress.
