[MOD RELATED] Error code 135:b1277437:2616a373

I'm having this issue as well. I think it is an issue with mods and cc, but whenever I try to use Better Exceptions to fully scan everything it doesn't state a specific mod that's causing the error. Only this:

Possible Cause: utilities\logging\version_handling.py\version_handling.py

Reason: [manus] Sim 243494094378830084 failed to load (KeyError: <Age.INFANT = 128>)

Custom content can get outdated with patches. If it works when you remove your mods folder, then one or more mods/cc is no longer compatible with the game and you have to find those.

Use the 50/50 method: http://modthesims.info/wiki.php?title=Game_Help:Finding_Problem_Custom_Content to find the culprit

It only happens when i try to select a household to play 

Just went though each of my mods to see which one was breaking. For me, it was LittleMsSam’s Calendar tweaks. I hope this helps for you!

Thank you so much, you are an angel, it is not possible to express my gratitude in English. It was the LMS. OBRIGADA ANJINHO ABENÇOADO

Yeah I have the exact same problem, did you fix it already?
