I was building my base and without advertising he comes in and completely destroys my base, I was building a wall and he knocked it down with a grenade launcher, 40 minutes of work gone.

I didn't screenshot him destroying my base but I did screenshot him killing me multiple times.
In the screenshots you will see him shooting at me,
(He has a gun out and there is clearly visible blood from where he was hitting me)
in the second screenshot you see that he killed me.

I'm sure you can check the logs for him killing me also.
