I baught 2 copies of Destiny in order to Play coop with my Girl. We have 2 PS4 and are connected via a router. As Long as we play independantly everything is fine, but when we make a fireteam and start a Mission we both get kicked after a couple of minutes with error codes "ferret" or "jackrabbit"... completely annoying as we only baught 2 copies to be able to Play together. already tried portforwarding one of the playstations, didnt help....any suggestions?
