You can try to manually backport USSEP changes, but that’s advanced. Easier: find older versions of those mods or stay on AE.
| Component | Required version | |-----------|------------------| | Skyrim SE | 1.5.97 | | USSEP | 4.2.5b | | SKSE64 | 2.0.20 | | Address Library | SE (1.5.x) | | Downgrade Patcher | Best of Both (if needed) |
Today, version 1.5.97 survives through "downgrade patchers" and community-led preservation. While the latest USSEP versions are built for the Anniversary Edition, the 1.5.97 patch remains a "legendary" file passed around by those who value the stability and compatibility of the pre-2021 era. It represents a moment in time when the community took ownership of the game's polish, even when the official developers moved on.
Update as usual. No issues.
