Hi, We have 2500 different customer groups in Magento. When we are setting up a shopping cart promotion and try assigning it to 2400 customer groups,Magento does not seem to save it. There is no error once you hit the save button however, when we open the promotion again, Magento does not seem to select all of the 2400. It only selects around 990 of what we have selected. Is there a workaround to solve this problem? Many thanks in advance.
