最终合成个数读取失败。

Error message

最终合成个数读取失败。

What it means

Thrown at the final verification step after the add/reduce fine-tuning loops when ReadCurrentCraftQuantity() again returns a non-positive value. The fine-tuning clicks (addButton 1614,672 / reduceButton 1074,672) are assumed to have landed, but the OCR field can no longer be read.

Solutions

1. Lengthen the Delay(200) before the final read so the quantity field fully re-renders after button clicks.
2. Confirm the add/reduce button coordinates (1614,672 / 1074,672) still sit on the actual buttons at the current scale.
3. Re-read once after a longer delay before throwing.
4. Guard the fine-tune loops so a click that changes the UI is detected (e.g. re-check we are still on the craft panel).

Example fix

// before
await Delay(200, _ct);
var verifiedQuantity = ReadCurrentCraftQuantity();
if (verifiedQuantity <= 0)
{
    throw new InvalidOperationException("最终合成个数读取失败。");
}

// after: one longer-delay re-read
await Delay(200, _ct);
var verifiedQuantity = ReadCurrentCraftQuantity();
if (verifiedQuantity <= 0)
{
    await Delay(400, _ct);
    verifiedQuantity = ReadCurrentCraftQuantity();
}
if (verifiedQuantity <= 0)
{
    throw new InvalidOperationException("最终合成个数读取失败。");
}

try { await SetCraftQuantity(target); }
catch (InvalidOperationException e) when (e.Message.Contains("最终合成个数读取失败"))
{ /* re-capture after a longer delay and re-read */ }

When it happens

Trigger: After the while-loops that click add/reduce buttons, ReadCurrentCraftQuantity() on Rect1080(1248,615,221,34) returns 0. Happens if a click strayed (e.g. opened another panel, dismissed the field), the capture is mid-transition, or OCR regressed.

Common situations: A fine-tune click hit a different UI element and closed/changed the craft panel; the 200ms post-click delay is too short for the number to re-render; resolution drift moved the field off the crop.
