I'd bet the uproar was mostly do to people only playing the [ERROR] end to chapter one, while expecting it to be the same size as all the other episodes, and not knowing about the new work done on said old episodes. Like, I'll admit that with the change in plans for where to end chapter one, I kind of lost track of exactly what was going to be in this update along the way as well, and was a bit confused until I went back to reread a few of the previous development logs, then I remembered what was up.
Anyway, I did highly enjoy what was added, and am very much looking forward to the start of Season 2 as well as Canterlot Exchange's first release!
