by Excalibur. Noticed on Reddit by Alex, the attempt to fix being
blasted twice by wielded artifact weapon when changing alignment
ended up preventing wielding other role's quest weapons. At the

This backs out that change and fixes the double-blasting correctly.
When uwep and uswapwep are tested in advance of the rest of invent,
mark them as already processed before entering the loop that checks
all not-yet-processed inventory.
