Not seeing duplicates here.
I was reading the command line parameters in the wrong order, which is probably the cause of your missing items issue, fixed now. I was testing using the internal defaults.
Also re-wrote the merge function now much faster, probably now as quick as you could get in a scripting language.
Plus a number of other tidy ups.

New version uploaded, same URL.

If you are specifying the files on the command line, they need to be in this order
Active i.e. ZTW.HST
Backup, something like ZTW_Backup_%random%.HST so each instance gets it's own backup
Principal i.e. ZTW_Principal.HST
Output ZTW_Principal.HST, unless you are testing, needs to be the same as Principal
