[Gameplay]- A bug with a bug-( Elise spider bug)

About 50% of the time when i use Elises w in human the spider moves in a completly random diection from where i directed, such as the complete oposite direction. Continuing from this about half of the time the space then glitch jumps from what ever way it when to the target location then exploding imediatly. this bug has effected my gameplay alot from jungle clears to ganking and i would love to see it get fix.
