Wooly Rhino Horn
 

These shouldn't be stackable.

I am not finding any evidence on Alla but... I have this screenshot from Mac server, of one of my mules:

The bottom left corner bag, is all Coldain Ring stuff. On the right, second slot down you will see the Wooly Rhino Horn non-stackable.

Know for sure it wasn't stackable on EQMac.

Fixed for next patch.
