Shaco clone not responding

Hey i play ap shaco a lot and i recognized a bug that i cant quiet replicate but it happens every 20 games or so. When i try to r click my clone to walk somewhere he just doesnt respond. I can assure that i didnt lag cause i could move the real shaco just fine. It wasnt specific if i clicked on a champ or on the ground he just would not move. Only after like 5 clicks he moved a bit, but when i then clicked a 6th time he would stop moving and responding again. The last time this happened i clicked on a champ that walked into a bush and i lost vision right after that. But i dont know if this was the reason why it happened. If you have any more questions regarding that problem i would be glad to help. (I dont know if this happens with lb clone too)
