This one is kinda weird, I've never seen it before so it may just be a one time fluke.
I was in a server just now, on pvk_arena, and I was a Captain. A berzerker started attacking me and killed me as soon as my parrot killed him, but according to the notice, the parrot killed him after he killed me even though it appeared to be the exact same time. Instead of my parrot dying, it flew around some more and attacked more people and I spawned with a second parrot but it couldn't be used - it would only call back the already fighting parrot. However, I was soon kicked because people realised that their attacks weren't hurting it even though they were clearly hitting it.
I rejoined and my parrot was still there killing people, but when I went out to the arena, it flew at me too for some reason. It wasn't doing any damage, but it was attacking me. Like I said before, I have never come across this bug myself or have never heard of it from others. I don't understand anything about it, and I tried taking a demo but I only got about 7 seconds in before I was banned.
-doesn't die/remove itself when I am disconnected
-second parrot view model after death
-attacks pirates (no damage)
