Encountered bugs so far

I'm playing on PS4 and encountered the following bugs:

1. At times my grenades won't go off. It's totally random when this occurs.

2. The invigorated rebel shield in combination with the healing bot is bugged. Every time the healing effect tics, my characters reacts like she's being shot and I see the blood spatter animation on my screen. The effect of the bot works as intended, but it is annoying. Because I can't tell if she responds to being shot or being healed.

3. The mission "Scrap the Whole Thing" is bugged. It simply won't start. Whenever I go to the highlighted yellow area, nothing happens.

4. The "Arena: 101 Keys Docks" mission is bugged as well. Whenever I want to pick the experimental weapon up, it puts me in an infinite animation loop. I had to complete the mission without using the experimental weapon.

5. This one is more of a request: Elite enemies (tankers, blacklungs and bulwarks) have too many hit points on their shields and regenerate them way too quickly. It makes those fight tedious and frustrating. (They were a challenge in D13 but never like this.) Especially when you have to fight two or three of them at the same time. I like a challenge. But fighting three bulwarks at the same time is just too much of a hassle and frustrating. My autistic tendency is the only thing that made me complete that mission. At the minimum these enemies should be nerfed so that they have a 10 sec regen delay on their shields or something like that.
