The same happened to me today while streaming... caused me to loose a heli, logged straight back into the server no issue, i've read that hack #2 and #3 are related to connection issues that are cause by some hacks, which would make sense as this is the first time i've streamed and it would be using a whole lot more bandwidth than normal... however i'd be interested to hear what battleye have to say about it as it's not a great thing to pop up on the screen when your trying to start a streaming channel!!
