[Gameplay] Shaco Clone can´t attack inhib/nexus/barell using "r" to control him

On shaco there are 2 ways to control your clone. Either click and hold shift and right click the target or click r when cursor is on target. Both ways are fine as long as you attack turrets, monsters, minions or enemy champions. As soon as you try to attack inhibs/nexus or gangplank barrels with "r" the clone won´t attack.

1. Summon your clone
2. Use "R" to control him and try to attack inhib/nexus or gangplank barrel
