Places of power challenge tier 3 broken?

I always do 3 stars, today I lost 7 times! It seems that zPalpi doesn’t work properly.
I use, as usual, R7 Palpi, R4 Vader, R7 DR, R7 Malak, R5 Badstila.
Please note that challenge 2 is won on auto 😒
Further, enemies randomly resist to fear (!) and they target Vader veeery often.
