You're probably missing a mod that updated for patch 7 thats in your list, or re-download the game first on Beta patch 6, not the normal patch 6, I would try everything first before you do the advice from the nexus devs
You might have to do an extra step and make sure you are in beta patch 6, and re-download the game on that version. Then try the work around he told us about.
Its literally on patch 6, but giving me the message of "mod saved enabled but not anymore" from patch 7 despite me confirming and triple checking that I am still on patch 6 so idk how true that statement is atm
