When entering an expiration date in the Lot Mass Change function or Characteristics change function, the year might default to 19xx. For example, you might set the date to 3/1/30 but the date then defaults to 3/1/1930 when you meant 2030. This causes your lot to be expired and unusable!
To resolve this, navigate to Administration> Administration> Global Settings
