Hi, I've a problem with cart rule combination. From now cr is for cart rule. I have a shop with a lot of cart rules and I need to set cr with incompatibility with other cr. So, i follow these steps: 1. create cart rules: for example three cr: a. buy 3 pen i give you 10%; b. buy 5 pen i give you a 15%; c. buy 7 pen i give you 20%. 2. ok, now set the compatibility: a in incompatible with b and c; b with a and c; c with a and b. What happen? With no reason the incompatibility section is filled with some old cr that i not choosen. So, what i do now, suppose to delete the extra cr not chosen, then save and remain, well the incompatibility section is filled again. And again the data are stored in cart_rule_combination table on db. There's a solution for this? PS v. 1.6.1.4
