I think you don't need to re-register as long as you did not missed trice. Missing one mandatory requirement is just what made you missed it but only the last round. We really have to double check everything 12 hours before closing. You should read now the ann on discord because we can earn now str thru stakes. I read there are another set of tasks on the official forum this week where you can regain the amount you've lost. Your signature slot is open too mate, I guess you got many opportunities. Goodluck!
