If you use a teleportaion script (which costs a big sum of money) to the model houses like Alakol Model House (not accessibles anymore) will you be able to make more teleportation scripts and sell them to make a fortune?
That's only slightly right Eddie. They could go and make a dozen, but only sell them one at a time. That wouldn't affect Supply, because people will not know how many there are are thus would not devalue them.
Most industries we think of as being based on "rare" materials are not nearly as rare as we are led to believe. It's controlled supply, nothing more.
If it's a script to an old housing area, you can't use the script anymore. It'll tell you it's impossible to teleport when you try to use it. (I'm assuming that's what you're trying to do?)
