i have been getting multiple caterpillar errors and ive reset and re downloaded the game from disc to system also completely factory reset my 360 re-entered my login info and downloads cleared the system cache, opened the port forwarding oened the nat the unpn etc so all ports are open nat is open and i have done every trouble shooting possible including reset my modem gateway i have done both wifi and hard lined into my gateway box and still get booted. it is clearly on bungies end for these plethora of error codes maybe they need to clean u their servers and add some patches and updates and dig further into their side of things, everyone is having issues and getting irate and very angry and displeased on xbox 360 xbox one ps3 ps4 etc. bungie is failing to be the best they can be and failing in solving these issues, so maybe if theyd pull their heads out their butt and actually give a damn for once these issues would get resolved.
