(GAMEPLAY) Rek'Sai-doesn't properly use second tunnel

So i actually have this happen to me a lot. If I click a second tunnel that is made near the end of my first tunnel while I am in the first tunnel I don't properly use the second tunnel. I will activate the second tunnel and the tunnel will go on CD but I will not travel through it. I noticed that this only happens consistently if I am rapidly clicking the second tunnel while traveling the first to try and get into the second tunnel as fast as I can. You will see in the video that the second tunnel is clearly off CD I will enter my first and then click multiple times on the entrance of the second. Rek'Sai will at first enter the tunnel and the tunnel goes on CD but then she just stops moving and pops out of the tunnel.

1. make a tunnel at base or anywhere on the map
2. when you get tunnel off cd go through the first tunnel and then immediately use tunnel when you get out of first tunnel making a second one in succession.
3. when both tunnels are off CD enter the first and while you are traveling through the first tunnel click on the entrance of the second tunnel multiple times. ( i tend to click it very rapidly because I want to go through as fast as possible)
4. become sad that you just wasted more time than if you had waited to click the second tunnel =(

I have tried this in multiple games and I added a link to a you tube video of it happening.
