I believe i found a bug in Destiny. As a level 3 Titan (on PS4), i was playing the mission "The Warmind" on normal. Towards the end of the mission, i was fighting some enemies in a small room just before the room with the device my ghost had to hack into. I threw a grenade into a group of enemies, and it bounced off one of them and landed in a small pool of water. The bug is that the grenade didn't explode. It was spinning around in the water for a few seconds, then just vanished. i'm not sure if the grenade was floating or sinking, the pool of water was shallow, ankle deep at the deepest part. anyway, i figured that's why the Beta is happening. i hope that a Bungie employee finds this thread before the game comes out. The surprising part is that there isn't a "report bug" feature in the game itself, luckily my computer was within armsreach. That bug caught this lazy guy at a good moment.
