Cam Rotation

In a lol game, You can rotate your camara and click where you want to go (near a torrent, for exemple) So, thats the issue, Sometimes when I play suddenly the camara rotation doesn't work, I have to click lots of times to get to where I want to because I cant move my camara to this area. I hope you understand what I mean, if you do I realy need help because when it happenes it makes me waste a lot of time just to get to the place I want to be at and disables my teleport option. Thanks!
