Problem with conversations on merged tickets...

Please correct this as soon as possible as we use our helpdesk conversations as evidence for our Sarbanes Oxley compliance:

Once a ticket is merged with another, the description of that ticket is shown as a "conversation" on the parent ticket. However, emails sent by clicking "reply" or "forward" on said conversation are not shown in the conversation section on either ticket.

As soon as the message has been sent in this manner, the contents of the child ticket are displayed and the conversation is absent from both.

The message is being sent correctly, but a record of this is lost. A possible work around is to only use the reply button below the ticket description or conversations that are linked to the original ticket, but without foreknowledge of the merge this may be overlooked.
