Normally we wouldn't recommend directly changing the _SYS_REPO tables, but for troubleshooting purposes can you try and change the ACTIVATED_AT column for the object which isn't working to something before December 1st. You can use a query like the following:
update "_SYS_REPO"."ACTIVE_OBJECT"
set "ACTIVATED_AT" = to_timestamp('2013-Nov-30', 'YYYY-MON-DD')
where "PACKAGE_ID" = 'applications.stocktoolmob.WebContent'
and "OBJECT_NAME" = 'index'
and "OBJECT_SUFFIX" = 'html';
