Nidalee Couger Form Bug

I do not know if the cougar form is bugged or not but when goes into cougar form in a team fight, I believe that the "Swipe" is bugged. I was in the middle of a team fight when I was support Nidalee and I went into the fight after throwing a javelin at . After I pounced on the team, I quickly mashed the "Takedown" and "Swipe" so that the Lichbane would prock and do a lot of damage. When I mashed the "Swipe" I noticed that it would never go off and it would seem as though it would not work in certain situations. I had my friend try it out as well and he also had the same problem. I don't know what is wrong with the ability but it seems to me that there is a minor bug that does not allow it to work at certain times. When in human form however I could freely use "Primal Surge" to heal my allies and myself. Thanks, Darblyh
