Did anyone, that upgraded from 3.4.x to 4.4., have an issue with their custom emoticons (used in posts) not being upgraded correctly? By that I mean that half of our emoticons, which use to reside in the "public/style_emoticons/default/" folder got moved to the "uploads/emoticons/" folder, with the group name (default) used as the file prefix, and their img src's corrected in the old posts, meanwhile the other half had it's URLs simply rewritten to the public folder (not the emoticons subfolder) and never moved, resulting in broken images in our forum posts? Or to make the question simpler: does anyone know how to change the URLs of custom emojis (with corrections to existing posts)? It use to be a simple matter of executing a content rebuild, which isn't available any more. Tried talking to the official support, but they keep insisting I give them access to our installation and I keep telling them I am doing test upgrades in a cloned virtual environment on my workstation and therefore can't give them access.
