Singed Q sometimes deactivates itself
So I was playing Singed the other day when I noticed that after activating my Q, I wouldn't be leaving a trail, because it was deactivated without be pressing Q again. I tested this a couple more times and the same problem a majority of the times, the Poison Trail would not stay on and turn off after about a second. Is this a bug or some mechanic i didn't notice? It's not just me clicking it again either because while testing I took my hands off the keyboard.
