Would there need to be an update to the mod fixer?
In my instance, I had one mod installed, without the fixer. The mod used the script extender to query if there any camp events. Prior to the patch 3 update, it was working as intended. However, after the patch, it became glitchy (NPCs/items non-responsive). It seemed like from the behavior the solution was to install the fixer. After I installed it, couldn't load a save and gave an error code 117.
