This is a great tool but it desperately needs an update.

This tool has a problem. I've been using it for a long time, but today it caused me a problem. The tool basically ALSO modifies the original files, which it's supposed to only read. I've tried all the various settings in the menu, unchecking the various options, removing or not metadata, etc., but nothing works. The original file is always modified, and the hash is different after creating the new custom MKV file. In my case, the problem is that it unnecessarily modified files I had seeded....
If I set the files to read-only, obviously leaving the option to remove it from the software unchecked, it crashes after the first mux.
