Shaco bugs (heavily gameplay differancing)

Me and my friend have been noticing a few bugs on Shaco lately, when it comes to aswell performance as the gameplay changing material:

All of the following things listed here below are recently found GAMEPLAY bugs

Jack in a Box: Doesn't prioritise, Doesn't take aggro, Bug that makes the box getting stuck in walls.

Deceive: Sometimes it doesn't make use of runes effects from infinity edge.

Two-Shiv Poison: Sometimes when you throw the dagger to the enemy which is about to die the damage won't go off.

Hallucinate: Sometimes the ult damage of the clone doesn't go off if the timer expires or just gets killed.
