Unfortunately, as part of the process we are performing, we will need to temporarily disable Custom Item Sets.
Once again, we apologize deeply for this inconvenience and we're working hard to get our servers stable Â– although we are unsure as to how long these repairs may take. We appreciate your patience through all of this!
