[GAMEPLAY] Ezreal BUG - sometimes stops walking after q

It happened in game, I was trying to stack my Tear of the Goddess so I spammed the q button as usual as I was going back to my Lane. Sometimes Ezreal just stopped walking. It has nothing to do with items or the q direction you fire it.

Reproduce:

1. Click somewhere on the minimap, which is far away from Ezreal.
2. Spam his q(He should stop for a second and after the q animation walk towards the point from step 1)
3. Sometimes (after like 5-8 q's) you should see that he stops, makes the q animation and then stops moving entirely.
