When Does the Credit Override Setting of an Order Automatically Change?

In our installation, we occasionally see orders have the credit override flag set automatically even when the account is on Credit Hold. Judging from the change logs we’ve set, it seems to happen most often when AutoPrintReady is checked on the order. Can anyone explain under what conditions this occurs? Is there any documentation available on this?

We’re using version 10.2.300.12.

It turns out this was caused by some custom code in a method directive that I wasn’t previously aware of.
