Ran a basic test with just USSEP and Water for ENB enabled, on the current release version.
Some cells that are broken:
x9712, 9713, 9732, 963A, 97A0
I see in the logs that's it's copying the esm data on the affected cells. Logs attached: https://www.dropbox.com/scl/fi/l3iymffwkb39y50jcjps8/OcclusionLogs.7z?rlkey=1wg3l4n7htww7oa51a9dirtoh&dl=0
Reran the test with the beta exe linked above, and all of the issues appear to be fixed. I'll give my full load order a test with the exe to see if the various Encounter Zones, EdIDs, etc. are also correct but it looks like it should be good now.
