We’re trying to host a project zomboid server on the latest build. (They just added multiplayer) Unfortunately, after getting the server to update to the correct version, it does not start.
The most reliable way to do that (and still keep your old stuff), is to put a new name (like servertest2) in the “Server Local Name” setting in AMP (under Configuration>Project Zomboid>Server)
Or if you just want to start over, delete the whole Zomboid dir, then update the server
