Same problem. I realized I had a bunch of partial downloads of previous compatibility packs that weren't showing up in my active downloads. Downloaded them all, thought it would fix it, but it didn't. Now I'm back to showing an update being the only thing destiny needs to download. Weird thing is that it failed due to oyster error but when I tried it again it said it was a 1.5Mb download instead of the previous 1.8Mb size. It must be downloading something.
