currently the Mod fixer and all related mods dont work ... Ive tried to start 3 new games with no luck.
Just updated my game, fired it up and the save loaded. I then updated my mods where available and again the save fired up. 25 or so mods installed.
Mod fixer is only needed if none of your mods does a forced recompile. I haven't needed MF since around Patch 2. If you do require MF then any version will do as the original code hasn't been updated or even changed since the original author moved on.
Have you checked on Nexus to see if any of the mods have been updated for Patch 3? Five of the mods I use were updated before Friday midnight.
Rule 1 of troubleshooting with mods:
Start a new game without mods.
If the problem persists then it is not the mods.
If the problem goes away then add mods one at a time and test.
Repeat until the problem mod or mods are identified.
