[(maybe a) BUG] Shaco's scary toys interacting weird with Dominion turrets

I've seen strange thing to happen:

Shace has planted that strange toy under our turret. I saw it thanks to turrets detection radius, and turret has been engaging it. But two things at a time were wrong:

1. That punny thing wasn't receiving any damage
2. When I approached it to smash it away, it feared me even though I could see it well

Also, I have tried to destroy these things on Summoners rift using 's Dark matter. They remained there. (I'm sure however, that I didn't miss)

Could anyone confirm? Could eventually someone add me in the game to test it, or test it himself using custom game?
