I have something extra details for this; The ADS shooting bug happens to me as well. My issue was initially a bit different, I have a steam controller that I play on through Steam itself; Whenever I go into a game or in the firing range, my gun starts shooting single shots randomly, with about 1 second in between. Then it pauses for a bit, like 3 seconds, then it starts again. This happens without any inputs from the controller or MnK. I tried checking controller inputs (thinking I might have my deadzones set too small) and nothing is being registered, also tried adjusting said deadzones but still it happens.
Also, this might be related (maybe some random input is being recorded from MnK), whenever I go into the EA menu inside the game (when I press right trigger), the glyphs are initially controller glyphs, then after some seconds (1-3sec, random each time) the glyphs change to MnK glyphs.
Now back to the initial bug, the controller is not sending out any inputs (tested) and i tried with and without steam layouts using the gyro/trackpads/capacitive sensor inputs etc. When disconnecting the controller, the random firing stops, but the ads firing bug still happens.
Pretty dissapointing since I just bought the battle pass yesterday and I wanted to try it out today.
Hi to the dev that has to read through this, I wish you good luck solving it =D
