My sim threw a wedding party at the house and then after that my game went completely haywire. I started getting SP script errors by the hundreds.  I've uploaded them to my mediafire as I'm still not sure how to do it here. I would appreciate someone telling me what the problem is.

How to do it here: Select all the xml files in windows explorer and drag and drop them all on to the text box. Done.

You have a caste with a skill level requirement. That feature has issues with Sims who have improperly formatted skills. You can safely ignore the errors or delete any castes that have skill level requirements for now.
 

Thanks chain.
