Everytime I start a bounty as Volt Prime, regardless of the faction it's for, regardless of the location, I start out 'unarmed', despite being fully decked out. It's not the end of the world because I can just equip the weapons but I always go in charging to the fight and I end up taking a few hits before realizing I'm not attacking back.
This has only started happening after the Whispers in the Wall update, and only for bounties (it happened during a profit-taker bounty as well). For normal missions this doesn't happen. As far as I can tell this only affects my Volt Prime, as my Titania Prime was unaffected by this issue.
