I don't know if the message on the main page is concerning this (since "the STEX being stuck in limbo" is vague), but I just recently went on a downloading binge and am trying to find dependencies for some lots.
The problem is that when I click on the link in the readme file it opens a blank page. Is this a new problem that will be fixed soon since SImtropolis was recently updated or what? Any sort of info is appreciated. Thanks
