yea we crashed into the hammerhead that we had destroyed. i'm assuming it was a physics bug on the basis that we ended up 7km away once our characters had regained their vision from the blackout (which was about 10 seconds after the video ended, e.g. we were flung 7km away in about 10 seconds).
A good way to tell if they're fighting AI vs fighting actual players are the name. AI has spaces in their name, example "John Doe" Whereas a player would have to do something like "John_Doe" or "JohnDoe"
