Stop using staff blocks for everything.

[Andre2006]

Those staff blocks at red fox are to prevent people from getting in, and im sure its the same with the mall, though I think they should really remove the "link" to the level so nobody can get in, then theres no need for those blocks

It wouldn't be hard at all to create a system for setting doors to allow staff only, or no one at all (if that's what you want).
