I don't think fate shrine and lucky trait are buggy any more since the Last patch. It is just hard to test, because of the event distribution over races issue. One problem with this: riots and rebellions, events create new races during the game, which changes the event distribution again and again. To test this issue, you need an event file with all rebellion events removed.
