This is just happen to me today, but i dont have an evidence on my account. However i just watch trick2g stream and found a bug similar to what i have experienced. So what happen is thresh hook didnt go all the way like it used to, it stopped half of its way and then hook a person like a magnetic.
I think that has to do with when the hook hitbox barely glimpses the edge of a champ's hitbox, most obviously when the champ's current animation puts their body far away from the point where the hook travels, however the hitbox doesn't move. It is just the barest bit of a collision coupled with the champ model being far away from the contact point due to the current animation playing.
