So i used the Ult with my ADC (Vayne) From Baron River Bush > To Enemy Base (South Base), and after the Teleport i was stuck on Camera Lock... i clicked Unluck Camera with hotkey . nothing happend. i clicked the button at minimap. nothing happend... this really threw the game because i coulndt see anything.. i was stuck in Camera Lock for the rest of the game :(
