Lost a Red-Crested Virmink, Tranq gun not effective

[bez8]

So i logged into Warframe and decided to go virmink hunting, I used Ivara and like the first day i was using sleep arrow and then tranqing them, turns out sleep arrow doesnt work on animals anymore and it causes animals to be invunerable against tranq darts. Fix this please I don't like losing extremely rare animals cause of a glitch :v

It's impossible to make them sleep with abilities anymore mate, sorry ! Try to look at my post, i'm making a list of the Warframes that DO work for capturing them more easily.
