2-18-2016 [Update] Match archive restore done, but...
We have now performed the backup restore of the missing match archive data, and it went well. We are still not finished though, since we are talking about 2 billion lines of text that now has to be reinserted into our archive database all over again. This will take approximately two days (a little over 50 hours remaining right now).
When it is done, we will try to complete all delayed "previous club" transactions. Also, all match related data should then be back to normal again. Thank you for your patience.
