未识别的副词条数值：{match.Groups[2].Value}

Error message

未识别的副词条数值：{match.Groups[2].Value}

What it means

Thrown when the minor-affix name was recognized (155 passed) but float.TryParse on match.Groups[2].Value (with '。' replaced by '.') fails under NumberStyles.Any and cultureInfo. The numeric portion of the affix is not parseable.

Solutions

1. Log match.Groups[2].Value to inspect the raw number text.
2. Ensure cultureInfo matches the in-game number locale; convert full-width digits before parse.
3. Pre-clean the value (strip spaces, normalize separators) before TryParse.
4. Fall back to RecognitionFailurePolicy.Skip if parsing remains unreliable.

static bool TryParseAffixValue(string raw, CultureInfo ci, out float v) =>
    float.TryParse(raw.Replace('。', '.').Replace(" ", ""), NumberStyles.Any, ci, out v);

When it happens

Trigger: The captured value contains separators or characters not allowed by NumberStyles.Any under the culture (e.g. a thousands grouping that the culture rejects); OCR inserted noise into the digits; the value is empty or non-numeric.

Common situations: Decimal/thousands separator mismatch between OCR output and cultureInfo; OCR artifacts in the number; full-width digits or other numeral forms not converted.
