When i upgraded my 10,000 kill Zhoulis bane that i got from pantheon, Explosive payload didn't enhance when i enhanced the weapon. it got rid of the masterwork border as well. if there was an option to reset it that would be cool too. i linked a reddit topic with 50+ people having a similar issue. https://www.reddit.com/r/DestinyTheGame/comments/1d86bl8/enhanced_perks_not_working/ would appreciate a fix been looking forward to it.
