Black Sun timeline boss just left the fight

I have no idea what the fuck just happened.
This dumbass bird just decided that I’m not even worth fighting.

After the attack where Rahyeh flies across the arena and leaves the black dot thing he just decided to not return to the middle.

Was around 22% hp left on the boss if that matters.

Fight counted as a loss.

Don’t have a clip of this actually happening but I took a sped up video of me running around after the incident.

Logs and the video mentioned above can be found in my drive folder

I’ve had this happen before. It’s when his charge lines up with the exit from the circular platform. However, you can also just leave the platform and go back to the start where he’ll be chilling until you interact with him again. Probably shouldn’t happen though.
