The only sieve script in use is:

if anyof( address :is "to" "akumria at acm.org", exists "List-ID")
{

       redirect "wildfire at progsoc.org";
       keep;
}

I'm not sure what you mean by your first question, but from what I
understand if there was no 'keep' in the above script I would not have a
local copy.

As I said, my suspicions are on 'mail_crlf_save = yes', since that *is*
specifically modifying the headers associated with the message.
