The problem is due to a set of changes I made which consolidated all of the zip extraction handling into a single implementation but there's a problem with how the information about the items that need to go into sub-folders vs when the new sub-folder to use is reported by the archive library which is causing some of the skins to fail to extract as it needs the sub-folder the exist before trying to save out the files but isn't getting notified at the expected time. Will get it fixed for the next build that I'm trying to get finished off asap.
