Mother Talzin zeta help

Hey forum attendees.

Looking to see if I have missed something with Talzin's leader or if this happens to anyone else.

Final wave in TB, Daka dead and only using basic abilities. Daka was only called to assist every second attack or so. No negative status effects on anyone, and it seemed random. For example, she didn't assist Talzin first time, but did second time.

Unfortunately I didn't get chance to record it.
