@EA_Atic It happens quite quickly, but if you pause the video at the start you'll see that I have exactly 8 flares, and the cooldown is just finishing. At just about one second in, notice that when you see that flare launch, the counter is still 8 flares, and the cooldown does *not* activate until just a moment later, when I shoot the flare from the main cannon toward 153* on the map's compass.
Two flares are launched in a short amount of time, and if you look at the cooldown once you have the flares equipped, this shouldn't even be possible. That very first flare at around one second was activated by tapping the smoke button. I'll get some more video of this phenomena soon if I can.
