Plurals half-working for 1 langauge and entirely working for another

Describe the bug

I have 2 languages, Croatian and English, on the English side all plurals are working as expected, on the Croatian side, half of the translations work (even when the same key is used!)

Occurs in next-i18next version

“next-i18next”: “^10.2.0”,

Code used

    const { t } = useTranslation("campaigns");
    
        const options = [
        { count: 0, duration: "day" },
        { count: 1, duration: "week" },
        { count: 2, duration: "week" }, // this doesn't work in croatian
        { count: 3, duration: "week" }, // nor this
        { count: 1, duration: "month" },  
        { count: 3, duration: "month" }, // nor this
        { count: 6, duration: "month" },
    ];

             <select>
                    {options.map((it) => (
                        <option
                            key={it.count + it.duration}
                            label={t(
                                "common:fields.items." + it.duration, //duration is month/week/day
                                { count: it.count },
                            )}
                            value={it.count + " " + it.duration}
                            className="w-full py-2"
                        ></option>
                    ))}
                </select>

And my translations are as follows

//hr/common.json
      "items": {
        "day_one": "{{count}} dan",
        "day_other": "{{count}} dana",
        "month_one": "{{count}} mjesec",
        "month_other": "{{count}} mjeseci",
        "week_other": "{{count}} tjedna",
        "week_one": "{{count}} tjedan"
      },
   
   
   //en/common.json
         "items": {
        "day_one": "{{count}} day",
        "day_other": "{{count}} days",
        "month_one": "{{count}} month",
        "month_other": "{{count}} months",
        "week_other": "{{count}} weeks",
        "week_one": "{{count}} week"
      },

@Nikola-Milovic did you open an issue on the main i18next repository? I can’t find it. If no, did you find out what the problem was?

The issue was with the language itself, basically Croatian has 2 plural forms.

"exclusivityPeriodItems": {
        "day_one": "{{count}} dan",
        "day_few": "{{count}} dana",
        "day_other": "{{count}} dana",
        "month_one": "{{count}} mjesec",
        "month_few": "{{count}} mjeseca",
        "month_other": "{{count}} mjeseci",
        "week_other": "{{count}} tjedana",
        "week_few": "{{count}} tjedana",
        "week_one": "{{count}} tjedan"
      },

There is both _few and _other forms, there is a specification for this but I dont remember the link, more languages have their own quirks.

I highly doubt this is an issue with next-i18next. Can you please open an issue in the main i18next repository?
