User-contributed fix; bypassed the contact form so no #Hnnnn number.
On the Gnome King's Wine Cellar version of Mines' End, a couple of
wall stubs in the lower far right were diggable, unlike all other
walls on the level. One single-spot wall stub was leftmost of three
undiggable spots, wall+floor+stone. The floor spot wasn't noticeably
different from normal (not sure whether digging a pit was prohibited)
but the stone one was.
Bustling Town can be generated with inaccessible areas outside the
top edge of the fixed town map. If you end up in one of those area
without any way to dig or teleport, you're stuck.
This adds a new level flag "inaccessibles" to force checking for
such inaccessible areas, and add secret doors, holes/trapdoors,
or some random escape item into the areas.
correct the region where the down stairs can be placed so they don't show up
in a cut off cave. If/when the level generator is improved to avoid generating
such caves, the down stairs region could potentially be changed back.
Add FOUNTAIN directives to the maps that just had '{' symbols.
Without them, the special level loader sets up those maps in a way
that prevents nethack from keeping the fountain counter accurately,
resulting in lack of fountain noises when they haven't been touched
yet and persistent noises after at least one of them has been dried
up. (It would be better to fix lev_comp's map handling code to do
this automatically.)
minetn-6 includes a MAP along with the flags that cause it to be cavernous.
However, the caverns get generated before the MAP is adde the level. Other
similar MAPs have open space on their edges, but there were walls on the
lower right edge of minetn-6. Added another column of mostly open space.
This level can still get cut-off areas, but the stairs won't be located there.
Give names to remaining town levels.
Change elements in College Town that don't follow theme.
Remove isolated niche and helm of brilliance from end #3.
This patch adds several new levels from <Someone>'s Gnomish
Mines patch, after devteam revision.
The ordering of levels in mines.des has also been cleaned up.
