Hello mateccm
unfortunately I have no good news.
If you have problems with a mod and removing it is either not an option or still causes problems,
please ask the creator for support. (unfortunately they are not always reachable anymore)
If you have a lot of mods, this will be even more difficult,
as their combination may also cause problems or the mod in question may be difficult to find.
You would have to remove mod after mod until the culprit is found, assuming the bug is not already permanent
SureAI cannot help you with things that we have not created and at least tested extensively.
Cheats or problem solutions with console are not recommended (and not always possible),
as they usually cause more problems and remain in the saved game.
In general, the wrong cheats at the wrong time can also destroy saves and get stuck there permanently;
this does not always have to be visible immediately.
Unfortunately, the chance of a successful repair is then very low.
Arcanist Fever is a script and not an ordinary spell. But in any case, the cause must be solved first.
