Questions

Questions and answers.

Where is SandboxVars.lua?
Beside servertest.ini, in the Zomboid/Server folder of the account that runs the server. Its name starts with the server's name, so a server started as servertest reads servertest_SandboxVars.lua.
Does a changed sandbox file affect a world that already exists?
Mostly, yes: in our tests the server read the file at every start. The start date is the exception: settings like StartMonth only apply to a new world.
Where do the presets come from?
Rising, Outbreak, Extinction and Six Months Later are the game's own presets, read from its files (Build 42, Steam build 25485538). A preset changes only the settings it lists.
Is this for Build 41 or Build 42?
Build 42, the default Steam branch. Build 41 is on the legacy41 branch, and its sandbox settings may differ.
