rcache bit wrong in set_field

It was doing

if ($field1 == 'id')

{ rcache_unset($table, $value1); } else if ($field2 == 'id') { rcache_unset($table, $value1); }

else if ($field3 == 'id')

{ rcache_unset($table, $value1); }

else

{ rcache_unset_table($table); }

The second and third of those should be using $value2 and $value3.
