Hi there,

I'm really enjoying the Battlefront II campaign, but I've noticed an issue I've started to face since last night. Whilst completing the missions on Bespin, I noticed the R2 button on my PS4 controller would not work any time I entered a vehicle (AT-ST, X-Wing etc). Either the guns wouldn't fire, or they would just start firing automatically.

I don't think this is an issue with my controller, as it works perfectly fine otherwise.

Has anyone else faced anything similar? Any help would be greatly appreciated!! Thanks!!
