Renekton "E" bug

Renekton's "E" will give a second dash as long as the first hits a target. After the completing a second dash the cursor remains as a target indicator instead of switching back to the pointing hand. When stuck in the target cursor, I was not able to use any forms of pinging or move my window on the mini-map. It was possible to reset this once in awhile by performing the two consecutive dashes. This unfortunately leaves moments where you cannot communicate changes in position etc. Riot, please investigate.

Edit: I did use the repair tool in between a couple of games and the bug was unchanged. No ping or performance issues noted while bug was occurring
