[Gameplay] Rengar ult indicator not working

During the last game I played (5/12), there was no indicator when the enemy Rengar was stealthed near us with his ult. This occured with every ult save for one, which he did not use to attack. Either the range of the indicator was somehow less than the leap range, or it was simply not working most of the time. One other player reported not being able to see the indicator, but another teammate said his was working as normal.

This obviously led to many frustrating deaths, so feedback would be appreciated.
