Reported directly to devteam, player observed that objects on the
floor had their bless/curse state change when reading a blessed
scroll of remove curse while confused. Message feedback mentioned
a silver saber being dropped. I didn't attempt to view the ttyrec
playbacks; what I'm sure happened was that the saber was secondary
weapon for dual wielding and had been uncursed; the confused remove
curse effect cursed it, which in turn caused it to be dropped. The
saber's 'next object' pointer became the [previous] top of the pile
at that spot and further object traversal intended to process the
rest of hero's inventory ended up processing floor objects there
instead.
This bug has been present for over 20 years (since 3.3.0 came out
in late 1999, when dual wielding was introduced and cursing of the
secondary weapon forced it to be dropped since making it become
welded was deemed to be too complicated) and never been reported.
Most likely players keep secondary weapons blessed so the scroll
effect doesn't touch them and simple object traversal sticks with
inventory. Or items at the spot have unknown BUC state so having
them be affected wouldn't be particularly noticeable.
