After 1.1.3, Molag Bal could not be fought because he would either drop people (where they would die, freeze, or become a string puppet), or hold them forever with no way to interact. A temporary hotfix was issued which fixed this for most, if not all. With 1.1.4, it is back to broken AGAIN. If a hotfix can be issued temporarily, but doesn't survive the next patch, why not just make it a permanent part of the patch so we can finish the main quest?
