Vraska's first ability is still bugged after the update.

i can confirm this.

I've noticed this as well. My opponent had Darigaaz's support and one treasure. I used her first thinking Darigaaz's support would get hit prior to his ability to return but no it has to hit the treasure. 

I have Vraska in the mid 50s and her first ability it at 4. So it should of automatically hit the support from Darigaaz.

Interestingly, at low levels, Vraska's targeting does not prioritize treasures. I had it take out my two shield Zhalfirin Void when I also had a one shield treasure.
