I have just read the  Rune Fragments  Chart  topic and discovered the real  reason I wasn't finding the fragments I was looking for.

Initially I thought there was a bug when unexpected pieces dropped from the ghost ,next that I had copied my own chart incorrectly, and transposed two of the items .when actually it is the game that has swopped two items.

Does anyone know when it was done and why, is there, was there an announcement about it ?

It might be difficult to program, but does anyone else think it would helpful if the fragments were segregated by Ghost type in the Rune Workshop?

The pieces are so similar  that when they are all jumbled up together its takes time to fathom what belongs where, and what to go for.
