I tried the Nightfall strike twice, and the daily four times, weird how every time I beat the final "boss" on each level I got kicked from the fire team and did not receive loot. Weird that I went onto another one of my Xbox live accounts (that did not have as high of a level), and the servers worked Perfectly! Wow, same Xbox, different accounts, different problems, obviously not my Wifi or Xbox, looks like its on you servers, and they want us to buy "updates" in the form of so-called "Extension Packs", amazing.
