Here is the master plan:

• The main towns (areas marked in red) will get regen every “7 Days” on “Fun Pimps Fridays”
• The areas marked in green I will try to keep safe for long term unless there is a patch that changes map features or adds prefabs so build there if you plan a long term base
• Other areas will be reset as necessary
• Area -3,2: Trespassers will be shot on sight; survivors will be shot again
