Hoxton didn't really do a good job at burning down the Laundromat. The safehouse is available as a standalone contract with the old tutorial being playable once per startup for all the veteran players who wishes to remember the old times without resetting their profile.

Yes, Team AI will be present, this is for anyone who would like a thorough test of the Crew Management perks/abilities without the cops shooting at you.

If you like to visit the old safehouse without the tutorial, please alter the tutorial.lua or get "Two Click Safe House"
If you want to replay the old safehouse tutorial without visiting it again, please alter everything else except tutorial.lua.
