I wouldn't be surprised if this was a lag based issue, it could also be apart of the double tap problem where you pay twice. In a couple of games today (Lazerazor in both), i've gone to the annihilator in the centre and used it. Just as I used it I got sniped in the face. The game then proceeded to take me $250, and not use the annihilator at all (still green, usable). Anyone managed to replicate this, or see it happen to another player?
this has happened to me once. it seems like the only fix would be to make it take money at the end of the annihilator animation instead of the start.
fyl Sakori: This is a known issue, make sure you see the text pop up and only press down on the D-Pad once. Also, this can occur on all the hazards/bot spawners.
