I have just crafted about 50 equipment master writs which I had saved for another XP boost event like now. I used a tool to keep track of all the items I need to craft and checked them off one by one. The weird thing is that when I dropped of the items at the master writs merchant, one item wasn't crafted. I can of course make a mistake BUT I am 100% sure I did craft that item as it was the last item on my list of items to craft and I was very conscious that I crafted and improved it as was required. But it wasn't in my inventory no longer when turning it in. I had already turned in several other master writs, so I suspect that a bug removed that last crafted item from my inventory when turning in another writ. Has anyone else experienced something like this too?
