Specially-named scripts aren't found

[Kebap]

In addition to #9 I now tested the following names (for triggers highlighting web-links etc.)

1. http(s) und www.lua (edit: My bad, this file 1 needed underscores and not space characters (stupid caveat))
2. mud@mg.mud.de.lua

Muddler finds the triggers.json and creates the objects alright, only they have no scripts inside.
Seems like muddler didn't find the corresponding lua files after all? Because of the @ character maybe?

Here is the relevant triggers.json excerpt for your comparison:

[
  {
    "name": "http(s) und www",
    "highlight": "no",
    "patterns": [ 
      {
        "pattern": "(?i:https?:\\/\\/\\S*)",
        "type": "regex",
        "comment": "accepted trigger types are 'substring', 'regex', 'startOfLine', 'exactMatch', 'lua', 'spacer', 'color', 'colour', and 'prompt'"
      },
      {
        "pattern": "(?i:www\\.\\S*)",
        "type": "regex"
      }
    ]
  },
  {
    "name": "mud@mg.mud.de",
    "patterns": [
      {
        "pattern": "mud@mg.mud.de",
        "type": "substring"
      }
    ]
  }
]

Am I doing it wrong?

Workaround: - renamed file 2 to not use "@" and now it works as expected
