Assault: Underbarrel Grenade launcher revive glitch & Switching class kits
Double binded equipment and secondary primary weapon when revived in the battlefield.
When playing as assault and you equip a grenade launcher under your primary weapon (attachment), you get glitched once you get revived by a medic or squadmate if you have a secondary primary weapon. This means on PC, if you're revived, the grenade launcher and secondary weapon get assigned to the same slot (Keybind Number 3 on keyboard). In order to switch secondary primary and grenade launcher, you have to press this button twice. It also doesn't show you if you have your secondary primary weapon equiped in the HUD once you equip it. This means you don't have bullet or ammo info about this secondary primary weapon. This doesn't happen if you use the grenade launcher standalone when you don't have the attachment equipped under your assault rifle or carbine. To test it out, die on the battlefield with the grenade launcher attachment on primary with a secondary equipped, then get revived. The HUD layout gets bugged and switching to secondary primary results in no HUD update.
Switching kits on the battlefield issue (only experienced as assault, might have something to do with the above)
When you are switching kits on dead players, for example, picking up a medic kit to deploy the resupply ammo/health box, and then switching back. Keyboard Number 4 on keyboard on PC, the assault class has an extra gadget that carries over from the kit you switched to and back. This means I can have more gadgets as assault than intended, I don't know if this happens exclusively when you have the underbarrel grenade launcher equipped and secondary primary. Because the assault gets an empty gadget slot when using this combination. To test out, find a kit on the battlefield with the assault class, with grenade launcher underbarrel and secondary primary, and then switch back to your deployed kit.
