I didn't shoot any rounds out of it

As you can see I got on it, I pressed four, move it a bit then I dismount

And also the firing happens when Dragon108 was on it

Look 3:48:14 and look at player Abuhajaar at main with sniper kit. And look who's at the mortar, Abuhajaar was the one complaining about being mortar'ed in main

Okay, I don't know how did I killed him, I think because I spammed left click to see if it's fire at the moment I mount it, maybe it has been aimed directly into the enemy main. As you can see I mounted it for less than 3 seconds, I didn't even aim the mortar.
