Polaris Lance' exotic perk often fails to work correctly and skips itself. Example - when i was running Zero Hour i was taking down bug shunks with Solar shields. After breaking the shield with PL i was goin after crits only, and sometimes at 1,2 or 3 "glowing lights" on the weapon they all would reset, giving no explosion bullet as a result. And this often happens in queries, giving no explosion bullets at all.
