What happens to a control ward after you place another one?
So say you put a control ward over dragon and silenced the enemy team's ward there. Then you noticed that your blue was gone and that the enemy Kayn took it. Which means he had the oppurtunity to place a deep ward and you want to make sure he doesn't have that vision on your jungle. You place a control ward and voila! Turns out he did place a ward there. But what happens to the control ward you placed previously over dragon? Does it dissapear? Does the vision stay but the enemy ward becomes unsilenced? What happens to a control ward after you place another one?
I is the only one with no cap. But let me check just incase its got a soft cap. Will edit after a test.
