Song info difficulty is doubled in v5 (Bug/Feature)

[t404owo]

Instead of showing this (output of v4):

{
"song_id":"any_track",
"difficulties": [
    {    
        ...
        "difficulty": 4,
        ...
    }
]
}

the output of the current version (v1.1.8) in v5 shows the following...:

{
"song_id":"any_track",
[
    {    
        ...
        "difficulty": 8,//(which is doubled)
        ...
    }
]
}

Is this a feature? Or else can you please fix this problem for the next version?

This is a feature in the new songinfo format of ArcaeaUnlimitedAPI. When the difficulty is an odd number, it means the ingame difficulty have a plus sign.

For example:

{
    "name_en": "Ringed Genesis",
    ...
    "difficulty": 21,    // means 10+
    ...
}

Is there any other question? If not I'll close this issue :)
