IGN actually did publish an article about Act 3 bugs on August 28, when we were still in Patch 2.

Actually, a few gaming news outlets seem to have published articles about Act 3 bugs in August and September (I am unfamiliar with most of these outlets and am unsure about their reputations, just FYI):

But there has not been a single article published about Act 3 issues since Patch 4 dropped, that I can find, which is very strange. Since Act 3 bugs seemed to be a fairly popular topic just a couple months ago.
