Subject: [PATCH] Fix the new rolling boulder traps for when monsters step on
 them

The traps don't disappear when stepped on any more; that should be
true even when monsters step on them.

(This bug was reported privately to me via IRC, rather than via the
devteam's email address, so there isn't a ticket number to close.)
