Is there something going on with the engine? Keep on submitting scores but always says calculating..... should I resubmit or just wait?

There seems to be always one submission 'blocking' the recalculation flow. I've removed it from the queue and made the engine recalculate the points. Should be fixed in a couple of minutes.

Is there a way to track down the result_id from the application_recalculation table?

In every case I've seen so far, the hw_id is missing from the table (NULL value).

Can't you find all of these entries by a search?
