Ever since the latest hot fix that stopped farming ether chests for treasure keys on patrol I haven't gotten a single one. I've done all the queens bounties on three characters and the only keys I've gotten are from turning the bounties in. I've opened about 15-20 chests since the patch and nothing. It was supposed to increase the drop rate for keys but it seems to have stopped them dropping for me. I can't even farm the chests after I kill the pack of wolves to try for a key, so I can't do Prison of Elders as much as I would like to because of this. Does anyone know why this is happening? If this is a bug Bungie can you please fix it so I can actually get the rewards when I do PoE without having to worry about the damn keys.
