Hi @srbarba , we cannot reproduce this scenario on current develop(3561b66).
You could disable all third party extensions, update your version of magento. Do composer install/update. Clear magento cache. Do bin/magento setup:upgrade.
If scenario will be reproducing again. Please add more details to steps for reproduce.
Thank you!

Steps:

1. Install Magento
2. Create category
3. Create 2 Simple Products
4. Create Grouped with this 2 Simple products.
5. Buy a simple product from the Grouped Product.
6. Invoice the order at admin with Copy email option checked.

Result:
The error at first comment.

Hi @srbarba , thank you for your video.
Internal ticket MAGETWO-54633 was created.

Hi,

Just to let you know I'm also getting this similar when you try and click on "send email" for an invoiced order.

I'm also using magento version 2.0.7

Fatal error: Uncaught TypeError: Argument 1 passed to Magento\Sales\Block\Order\Email\Items\Order\DefaultOrder::getItemPrice() must be an instance of Magento\Sales\Model\Order\Item, instance of Magento\Sales\Model\Order\Invoice\Item given, called in /Users/chris/Sites/magento_test/vendor/magento/module-sales/view/frontend/templates/email/items/invoice/default.phtml on line 34 and defined in /Users/chris/Sites/magento_test/vendor/magento/module-sales/Block/Order/Email/Items/Order/DefaultOrder.php:97 Stack trace: #0 /Users/chris/Sites/magento_test/vendor/magento/module-sales/view/frontend/templates/email/items/invoice/default.phtml(34): Magento\Sales\Block\Order\Email\Items\Order\DefaultOrder->getItemPrice(Object(Magento\Sales\Model\Order\Invoice\Item)) #1 /Users/chris/Sites/magento_test/vendor/magento/framework/View/TemplateEngine/Php.php(59): include('/Users/chris...') #2 /Users/chris/Sites/magento_test/vendor/magento/framework/View/Element/Template.php(255): Magento\Framework\Vi in /Users/chris/Sites/magento_test/vendor/magento/module-sales/Block/Order/Email/Items/Order/DefaultOrder.php on line 97

Thanks

Hi,

Btw - The problem is the Magento\Sales\Block\Order\Email\Items\Order\DefaultOrder::getItemPrice() method.

public function getItemPrice(OrderItem $item)
{
    $block = $this->getLayout()->getBlock('item_price');
    $block->setItem($item);
    return $block->toHtml();
}

If you take off the Type hint OrderItem $item for the argument and just have:

public function getItemPrice()
{
    $block = $this->getLayout()->getBlock('item_price');
    $block->setItem($item);
    return $block->toHtml();
}

it works fine

Also this is in magento 2.1.12 as well
