I'm getting a server error every 5 minutes when the world tries to save... System.IO.IOException: The process cannot access the file 'C:\Users\[Me]\Desktop\KMP Server\KMP_universe.db' because it is being used by another process. at KMPServer.Server.hostingLoop() at KMPServer.ServerMain.hostServer(ServerSettings settings) Stacktrace: at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.File.Delete(String path) at KMPServer.Server.backupDatabase() at KMPServer.Server.handleCommands() Any ideas?
