Missing PKHeX.Core.dll

[ABZB]

The hotfix release 19.11.15e is missing PKHeX.Core.dll

I am getting the error:
 

Exception Details:
System.MissingMethodException: Method not found: 'Void PKHeX.Core.SaveDataEditor`1..ctor(PKHeX.Core.SaveFile, PKHeX.Core.IPKMView)'.
   at PKHeX.WinForms.Main..ctor()
   at PKHeX.WinForms.Program.Main()

When I try to run Pokehex.

The dll isn't required; don't reuse old release data.

Got it, thanks.

I'd been extracting & overwriting updates into the same folder, to keep all my file paths the same...
