@datakick thank you very much for the message. The creation of dummy addresses itself does not bother me, however, as I mentioned, there are situations (rare, once in a few dozen/hundred orders) in which when the customer already registered places an order, he gets the data of the previous customer in the confirmation in the address fields. At first, I suspected that it might have had something to do with clearing the database on the 2nd website with PSCleaner, however, recently this problem also occurred on 1st store, on which we never cleared the order databases. Given the fact that we use Chex on both stores, I thought this might have an impact on this problem. Do you have any suspicions about what might be causing such a problem? Thanks in advance, the module is great, we would just want to fix that issue, since that's quite a critical one.
