If you add something like "<SSEEdit Path>\Cache\" to the arguments in the setup for SSEEdit in MO2 those files will be dumped into a cache folder within your SSEEdit folder rather than the overwrite folder. They are cache files which will speed up the initial load of SSEEdit. They've fallen behind. There hasn't been word from SirJesto as to any updated release date. It'll happen when it happens. Having said that, you can go ahead and start setting up the guide. When LotD v5 hits, it will hit with all new patches and all that is necessary. It should just be a matter of replacing the current version with the new version, installing the patches, redoing the merge, and start a new character.
