After importing my forums to XF I needed to correct a large number of invalid internal links - namely smilies. To make short work of it I used the Post Content Find/Replace add-on, which worked like a charm. Only it left a edit history behind. On every post that had a little smiley face there is now a 'Last edited by a moderator: Nov 19... blah blah' - this looks kind of bad, like I'm running around fiddling with posts from years ago. I don't want to trash out the site edit history just for this though. Can I remove the matching rows from the xf_edit_history table to resolve this (it was done as a bulk change, so they all have the same timestamp and editing userid, easy to select the rows) or is it more involved?
