Make sure the format is consistent across the lines.

The most common problem I see is regarding the resource.cfg file - if the resource.cfg settings in MO are not correctly typed or not have the additional lines added for your cc to be seen across multiple folders, then they won’t show up! Resource.cfg Paths and Additional Lines for S3MO and CCMagic Keep them in Mods>Packages for them to work properly. Even if you increased the limit size to 2000MB (2GB), you are still trying to merge the files together and they’ll still be larger. If you have any of the 5 large Store Updates (see screenshot below), do not add them to MO folders, you’re essentially trying to merge already merged files! The sizes of them (over 1GB!) are larger than the default limit size (1000MB=1GB) of MO merged files, so they will cause a crash. If you want those, ask Gokur, the creator - he does listen to requests! You add all your rugs to that folder, but you can’t have rugs in subfolders inside ‘Rugs’ such as Persian, Antique, Modern etc, as they won’t be seen. So for example, you have a folder for ‘Rugs’. When adding your cc and mods to MO, you can only add them in single folders (if you want to have categories), NOT nested folders.

These are problems that I didn’t make clear in my tutorial or even forsee would be a problem (my apologies!). There are some common problems that I’ve seen why S3MO won’t work for some people, not show all their cc/mods or cause crashes.
