When you try to create a contact in LCRM and receive the error message:
"Review all error messages below to correct your data. Apex trigger cv.ContactAll caused an unexpected exception, contact your administrator: cv.ContactAll: execution of BeforeInsert caused by: System.NullPointerException: Attempt to de-reference a null object: Class.cv.ContactUtils.autoCreateHousehold: line 1214, column 1"
The reason this error would be thrown is if the name of the Record Type of "Household" or "Organizational" has been changed to something different then it disable the triggers that create contacts.
You will need to change the record type name back to household or organizational.
