GAMEPLAY (BUG, ISSUES)

So I was playing as Janna and a teamfight broke out and my adc Kalista and I were mowing down scrubs. We saw there was a straggler Nidalee in cat form pouncing away. Kalista ulted me and I clicked on to Nidalee, as well as zephyr mashed her. Not only did it not knock her up but I also was brought back to kalista... sadly no penta but I hope this will be resolved. It has only happened to me once, though l'll try to reproduce it myself.
