This hotfix should not have been necessary, at least for the crafting station bug.
1. The developers who work on the crafting station changes for the new Nirnhoned trait should have seen and fixed this bug before the code ever left their desks. Opening the Creation screen at a crafting station and then clicking one button is all that is needed to see the bug.
2. The ZOS QA team should have caught this bug for the reasons listed above. The ZOS devs should pay attention to the ZOS QA team, if one actually exists.
3. The bug was reported by players (including me) on the PTS over three weeks before the update reached the live server. Somehow ZOS can't fix a bug in over three weeks if it is reported on the PTS but they can fix it in two days if it is reported on the live server. My head is still spinning about this fact.
