Subject: stolen_value() vs containers
X-Git-Tag: NetHack-3.6.2_Released~119^2~2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=5f5f7f63f1b0923149f91d1645f2af508a0713b6;p=nethack

stolen_value() vs containers

stolen_value() treated hero-owned container holding shop-owned goods
as free for the taking.

The fix I'm working on which led to discovering this first added
stolen_value() then eventually stopped using it so I don't have an
example of where it is giving the wrong result.
