Caution for users that are already using or plan to try out one or more of the new collections for mods here at Nexus. It should be no surprise to anyone that many if not most collections will have USSEP included especially those intended to be a one stop click for all mods in your game
Today out of curiosity I filtered the collections available based on popularity and downloads and discovered that only one out of the top four that came up for me that include this is actually set to install the latest version. The other 3 and many others I looked at will install an older unsupported version of this in your game right now
If you are using a collection or plan to use one that includes this mod here is how you find out for yourself what version of this is installed. On the collection home page click "Mods" to see all mods included in that collection. They are currently sorted by alphabetical order of mod name so scroll down until you see this mod and click the little triangle to the left of the name to expand. This will then show you what version is installed if you use that collection. One of the collections that showed up on the first page for me will install version 4.2.5b of this mod in your game if used -

You should not assume that a curator will keep the list current for this or any other mod and in fact that collection I took the example image from was updated in the last few weeks so is intentionally installing an older version of this in your game without telling you in its about section
