Twice today I've had payments from Authorize.net (SIM), but the orders are missing. Debug modes was on and these are the last 2 lines:

[HashValidationValue] => 5AAC581C2A8477E26DE8F1F4EFA3CED6
[HashMatchStatus] => FAIL


Would the [HashMatchStatus] => FAIL be the cause of no order created? And why would it have failed?
