A problem with Camille's E

Hey there,

I've been noticing quite a few times a bug on camille's E. As you know, it's a 2 part spell, hookshot, and walldive. Sometimes, after casting hookshot, you get pulled to the wall and then the spell ends without giving you the opportunity to walldive so you're just pulled to the wall and then you walk away (luckily you're not stuck on the wall for 1 second at least). And of course, the mana cost and cooldown are used.

Here's a replay to give you an idea : https://my.mixtape.moe/whhnbr.webm

This is not due to an interaction with any champion since i could do this on my own in Practice tool. However i have no idea what triggers it, or if it just happens randomly. Either way, it's really game changing and as you could see it killed me there. If you have any further info concerning what triggers it, it could help me.

Hoping it get fixed soon.
