Subject: Fix panic on thrown potion of acid when swallowed
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=af7db2f8f1df2a77f30f52589832a74cf5408e53;p=nethack

Fix panic on thrown potion of acid when swallowed

When you're swallowed and throw a missile that kills the swallower,
the thrown missile is picked up by the swallower before death.
This caused a panic when you threw a potion, which was first picked up
by the swallower, which upon death dropped the potion on the floor,
but then throw code was trying to destroy the potion ...
