When I try to unravel Tattered Wildercloth or Wildercloth (both from bank and from reagent bag) I get this error:

It also happens when I select the item from the drop-down list.

I've also tested:

1. Disabling all add-ons (no error)
2. Re-enabling only TSM (no error)
3. Re-enabling only TSM & Craftsim (error)
