The bug regarding 'new character' should be fixed by now, but the various 'errors' that you see regarding the image is due to our ongoing redraws. Some clothing items also has new code names which resulted in the alert box shown in your screenshots.
Once the redraws are finished we will be adding a compatibility layer to automatically adjust older files to the new version without losing any clothing items, but that's still for the next time.
Thank you very much for your detailed info, and sorry for your inconvenience!
