The Archfey warlock sub-class is still not getting a new cantrip at level 4 like the other warlock sub-classes and spell casters. This has been broken since release, and since that's the class I'm playing, I put my game on hold until its fixed. I've sent 3 bug reports about this through the support site, one when I first when I discovered it, and again for each patch that didn't fix it. I have not received any response, where other bug reports I've sent I have gotten replies within a day or two.
