Hi,
I notice a bad behavior of you payment points plugin.
So, first i have this first points situation
I have this setting on your plugin
I do a purchase of Euro 15,40 plus Euro 8 of shipping cost: the total is 23,40 - euro 1,80 for 36points = Euro 21,60
I set the order to payed and i have this situation
Then i set the order to confirmed and i have this
Finally i set the order to shipped and the final situation is
The sistem gives me an amount of 72 points
But i must have only 15 points that are the points of my last purchase.
What's wrong?
