You can still chase the 1000x, because there is a rule says In case of a draw, both will share the prize, you lost the bonus prize only if there is someone submit the 1,000x earlier than you.
But maybe LM can clarify which prize will be shared if there is a draw, is it the 1st prize only or the sum of 1st and 2nd prize?
Not only you, I'm sure many players experienced the same thing including me LOL
Sometime the 1000x come few bets after we lost our whole balance, or it comes earlier before we start our session
I experienced these 2 moments in the 2nd round some time ago.
