Bot games are getting possessed buy ghousts!

I dont have images or video for proof thats why im posting this in Misc, but at home we usually go premade for bot games.

This morning bot walks until he starts attacking minions just in front of the range of his inner turret, he stops but his orb of shield from his turret continues moving empty by itself and disappears on the middle of the map.

Just now we attacked bot, red damage numbers goes off, shows damage dealt to him - he does not take damage... The bot returns to base.... Unharmed.
