This is probably the worlds shortest patch but I will post it anyway. The
reason I added this was because I found it odd that you would want a room
to be indoors and not indoors at the same time. Pretty much why have two
flags for the same thing. Here if the sector type was indoors then I set
the indoors bitvector also. If you want to add this then just open up your
db.c file look for the bottom line and add the other three right above it.
It should be in the parse_rooms function.

+  if (t[2] == 0 && !IS_SET(asciiflag_conv(flags),8))
+    world[room_nr].room_flags = (asciiflag_conv(flags) + 8);
+  else
     world[room_nr].room_flags = asciiflag_conv(flags);

It worked for me, I hope it works for you also. If you would like to tell
me why this is stupid or congratulate me for destroying your computer or
my recent winning of the 'official shortest patch of all time in the field
of muds or mudding' then I guess you can e-mail me at:
