Stockable Variants - Child Product Quantity Ranges do not work

[beachy]

Hi,

As far as I can tell if you set up a  child product (stockable variant) with quantity ranges VM will not calculate the correct price.

Example:

Parent Product: Drill ABC

Child Product: Drill ABC 12V
Qty 1 -9 = £ 30.00
Qty 10-99 = £ 25.00

Child Product: Drill ABC 24V
Qty 1 -9 = £ 35.00
Qty 10-99 = £ 29.50

I have tried every combination possible but if the child product has the quantity ranges applied VM does not calculate the correct price but instead displays the lowest quantity break (highest price).

If I set up a standard product with a quantity range the correct price is calculated.

Has anyone else got this problem or found a fix?
