[CF-Devel] bugfix: unique maps

[Michael Toennies]

Hi Andreas

Yeah, but remember this damn password/teleporter bug in wizard tower for
example.
it *can* be used for dupe crashin, while is common with 2 persons.

I think, we should make a party at MiDS server one night. Let him compile a
debug version,
which logs all fucking steps we do. Then enter the tower end let teleport
and jump us
like rabbits. I like to see the log files then. Perhaps we got it in this
way.

      NO. The problem that you describe has nothing to do with my

      bugfix. And it has nothing to do with perm. apartments either.

      You can do it on any map: Save, pass stuff to other character,

      There´s only one way to prevent it: We must whipe out point 5) -

      I bet this one is easy to fix, but I can´t debug under linux
