New carts linked to old orders

[sallen_acs]

Hi there!

 

i had a PS 1.6.1.13 with this problem, when we try to make a new order from the BO, sometimes it assign this cart to old orders.

 

So it cause some problems to make the order, also to delete this carts is not possible (or easy).

 

i had clean the cart table, because it was too heavy on the database, i think there is the way to follow.

 

Maybe theres a reference of the old order to the "old" cart, and now, with the cart table restart, when it takes the same cart number it links to the old order?

 

Anyone know where could be this vinculation?

 

Thanks!
