Training dummies vs shaco clone

's clone (R) deals no damage to dummies whatsoever. I tried AD, AP... , etc. etc. and this is what happened: clone didn't proc effects, did no damage with basics, it somehow managed to stack passive however, but damage was still non existent... I also tried , and still no damage from the clone... then i thought since it stacks it should stack 's effect as well right? wrong... so to recap all that, in training mode, on enemy dummies, 's ultimate, does no damage with basics, neither with aura damage items... only thing it does is stack 's passive. however the issue seems to be only while clone is alive, and only towards dummies... when clone dies, the AOE damage is still there and the mini boxes work as per usual as well...
