I hunted outside of Thebes for awhile, and obtained few low grade pieces and combined them.
Then, I went inside and obtained few high grade pieces. Never saw high grade pieces in my inventory, but I had pets with me so figured they must be with pets. When I collected them, none of those high grade pieces came into inventory.
I wonder if there is any interaction between having low grade pieces in the inventory and obtaining high pieces?
If you could look into this at your leisure, would appreciate it.
