Connection went down once so I had to reinstall the game again?

So I come home from vacation, and I download the newest patch. I have 5 seconds left and my connection crashes. It comes back in an instant and I see that I had to install the game again along with the new patch..... This is going to take me quite a while. Reporting this issue so others don't have to experience it. Please Trion, make it a priority to fix your patcher.

Could be your issue.

Either way the patcher is still bad. So my point still stands. Also I don't think it's my issue, this is a brand new Microsoft official hard drive I bought for this game. My Xbox is also only a couple months old. It's the halo 4 edition.
