Bard ult on tower bug

When using ult on an enemy tower to engage, the laser targets Bard or whoever damages the enemy and does not disappear.

The ping of the tower spams for at least 5 seconds or more (for me). I've also had games where the laser stays onto me for more than a minute, revealing my location. It eventually goes away, but this will happen multiple times when using ult on an enemy tower.
