Using the hashes is fairly simple - see
http://wiki.mudlet.org/w/Manual:Mapper_Functions#getRoomIDbyHash. You'd
want to use Mudlet's createRoomID() function which generates incremental
room IDs for you instead, and assign the in-game room number to the
created ID with setRoomIDbyHash(). Then you can use getRoomIDbyHash()
with the in-game room ID to get the Mudlet room ID back.

Title:
  Too large room IDs eat too much memory

Status in Mudlet the MUD client:
  Invalid

Bug description:
  Double-clicking on a room in the attached map will cause Mudlet to eat
  up all memory (indefinitely). This is using current SF git.

  
  double click x=370 y=491
  Qt has caught an exception thrown from an event handler. Throwing
  exceptions from an event handler is not supported in Qt. You must
  reimplement QApplication::notify() and catch all exceptions there.
