Hi stevieb, thanks for your quick answer

Which file do you need? The "magic" one?

I think my instance is not really relevant. The important fact is the first byte in the file is 0x0A (then 0x23 0x2d 0x2d ..., i.e. line 2 is a standard comment starting with a "hash" character).

Since this is my first contact with the site, how can I attach this ~50k file to my post?
