Without being a 100 percent certain, being in the thick of some cutthroat matches with my friend when the situation arose,I'm pretty sure I've experienced this issue often.
Not that there's a legitimate reason how it could happen this way...but I keep wondering if the smoke isn't showing up when I scroll onto the screen right after the officer pops it. I know it dissipates before it lands(or I think it does), but I'm talking about a lengthy window of no warning before it finally drops on top of my units, that I was sitting there babysitting.
