Toying around with modifying the LORE flag for the purposes of another thread, I discovered that the PEQ database (as of the PEQ_Kunark_RC1 version anyway) is not up to the current standard for flagging artifacts properly. Thus, no items have the artifact flag in that database. Here's a MySQL query you can run to fix your artifacts:
Code:
UPDATE items SET artifactflag=1 WHERE lore LIKE '#%";
