Recently we have had two instances where a SR invoice and an SO invoice both posted with the same number. In the first instance we were releasing and posting an SR in one location a releasing an SO in another (we have Evo set to issue SO # at release.) In the second instance, we started releasing and went to post an SR and received the notice that someone else was posting. Indeed another person was posting, so when she was finished we cleared the notice and continued posting the SR invoice.  
 
In both cases, the customer account info is correct, showing what they owe. But the invoices have the lines from both orders on them and the total from the second one posted. We don't know what to do about these (can't void an SR), so we are waiting to see what happens when we receive payments against the invoices.  
 
Question 1 - should we void an reinvoice the SOs involved? Or will we mess up the SR invoices?
 
Question 2 - we are up-to-date with all patches, but I seem to recall this being patched recently. Is this a new bug we've found or the old one?
