Stormtroopers broken

It happened first with Han Solo while trying to fly out in the Falcon. Enemies would just run towards you completely mindlessly from all sides. I was able to move pass this one, but trying to reach the platform on Under Covered Skies is impossible. I even tried multiple times to stealth killed all enemies, so the enemies don't get alerted. There's no challenge, it's just very frustrating. It's making me wanna quit the campaign altogether, which is bad because up to this point I was really enjoying it.
