Basic Weakness not copied to enemy cards in rcore

Check

vs
https://arkhamdb.com/api/public/card/01599

Also on website:

These cards are defined only as clones:

    {
        "code": "01599",
        "duplicate_of": "01099",
        "pack_code": "rcore",
        "position": 99,
        "quantity": 1
    },
...
    {
        "code": "01603",
        "duplicate_of": "01103",
        "pack_code": "rcore",
        "position": 103,
        "quantity": 1
    },

So there must be something that doesn't copy Basic Weakness subtype for Enemy type cards.

I think this also happens for Assets and Events (rcore Investigators' Weakness cards).
