I am having an issue while following OPERATIONiDROID's guide to dumping and randomizing pokemon sun and moon. I am using sun and when I open pk3DS and click Pokemon Sun Dump, it gives me this error, and also says "Data Found! Loading Persistant" Exception Details: System.ArgumentNullException: Value cannot be null. Parameter name: source at System.Linq.Enumerable.FirstOrDefault[TSource](IEnumerable`1 source, Func`2 predicate) at pk3DS.Core.GameConfig.InitializePersonal() in C:\BuildAgent\work\b93f10d64d1a1178\pk3DS.Core\Game\GameConfig.cs:line 104 at pk3DS.Core.GameConfig.InitializeAll() in C:\BuildAgent\work\b93f10d64d1a1178\pk3DS.Core\Game\GameConfig.cs:line 98 at pk3DS.Main.openQuick(String path) in C:\BuildAgent\work\b93f10d64d1a1178\pk3DS\Main.cs:line 219 at pk3DS.Main.B_Open_Click(Object sender, EventArgs e) in C:\BuildAgent\work\b93f10d64d1a1178\pk3DS\Main.cs:line 108 at System.Windows.Forms.ToolStripItem.RaiseEvent(Object key, EventArgs e) at System.Windows.Forms.ToolStripMenuItem.OnClick(EventArgs e) at System.Windows.Forms.ToolStripItem.HandleClick(EventArgs e) at System.Windows.Forms.ToolStripItem.HandleMouseUp(MouseEventArgs e) at System.Windows.Forms.ToolStrip.OnMouseUp(MouseEventArgs mea) at System.Windows.Forms.ToolStripDropDown.OnMouseUp(MouseEventArgs mea) at System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ToolStrip.WndProc(Message& m) at System.Windows.Forms.ToolStripDropDown.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) Loaded Assemblies: -------------------- mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 C:\Windows\Microsoft.NET\Framework64\v4.0.30319\mscorlib.dll pk3DS, Version=1.0.0.80, Culture=neutral, PublicKeyToken=null C:\Users\User\Desktop\pk3DS.exe System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 C:\WINDOWS\Microsoft.Net\assembly\GAC_MSIL\System\v4.0_4.0.0.0__b77a5c561934e089\System.dll System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 C:\WINDOWS\Microsoft.Net\assembly\GAC_MSIL\System.Windows.Forms\v4.0_4.0.0.0__b77a5c561934e089\System.Windows.Forms.dll System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a C:\WINDOWS\Microsoft.Net\assembly\GAC_MSIL\System.Drawing\v4.0_4.0.0.0__b03f5f7f11d50a3a\System.Drawing.dll System.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 C:\WINDOWS\Microsoft.Net\assembly\GAC_MSIL\System.Core\v4.0_4.0.0.0__b77a5c561934e089\System.Core.dll System.Configuration, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a C:\WINDOWS\Microsoft.Net\assembly\GAC_MSIL\System.Configuration\v4.0_4.0.0.0__b03f5f7f11d50a3a\System.Configuration.dll System.Xml, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 C:\WINDOWS\Microsoft.Net\assembly\GAC_MSIL\System.Xml\v4.0_4.0.0.0__b77a5c561934e089\System.Xml.dll pk3DS.Core, Version=1.0.0.80, Culture=neutral, PublicKeyToken=null C:\Users\User\Desktop\pk3DS.Core.dll -------------------- User Message: An unhandled exception has occurred.

Ok. That's all I know about that because I never had any issues with PKHeX. Sorry and I hope you can fix your issue!

Did you export main or export backup? Backup for me always said save data was corrupted but never actually was, I restored my save with JKSM and used PKHeX and exported main and it worked fine...
