Hi everyone. That is a bug issue with firefly perk. A lot of people are saying that using a weapon with firefly perk makes the game suddenly freeze (X1) or exit with generic error code (PS4). Apparently it's not related with any other perk or weapon/class/armor. I'm using The Vanity hand cannon but there are more reports with scout rifles etc. To test this is easy. Just go to sing place with a lot of enemies and start to kill them with precision shots. Eventually it will trigger the game crash. It happens in all platforms. BUG #2: Apparently firefly explosions are bugged too. Some are bigger than its supposed to and the place when where the explosion occurs is not correct. You can find some YouTube videos with this too. I hope bungie can see that people are reporting this. Regards
