I am constantly being kicked from the game (back to orbit). The error that comes up is that I have left my fireteam and been returned to orbit just like if I left my fireteam during a mission, except this occurs during solo play and during matchmade sessions when I haven't left the team. It appears to occur every 1-10 minutes, occasionally not occuring for 30 or more minutes, although that is rare. This began after I downloaded the two expansions just recently. I have attempted to uninstall the game and reinstall. I have checked my connection type (open NAT). Destiny is the only game that I have a problem like this on. I can play MP in other games without issue. Twice when this has happened I have gotten error codes, one of which was caterpillar. I don't remember the other one. I'm happy to provide any additional information that might help if I have it.
