When I'm in a fireteam with my friend (and only when I'm in a fireteam) I get constant network issues with no consistent error message. We will sometimes desync and then will appear to be standing in place, or walking off the map, or dead to the other person when we are actually just playing normally. Activating a super or killing enemies sometimes seems to fix it momentarily. Other times we will load into a mission only for it to just send us back to orbit (which is particularly painful as we're trying to get whisper of the worm). We have tried restarting our computers and even changing our NAT types to open yet nothing seems to fix it. When we aren't in the fireteam everything works as normal. Does anybody have any idea what might be causing this or how we might go about fixing it.
