Last time I asked, why we should claim and donate already, if we are not live yet and you said, that there will be a replay.
It doesn't seemed to be a replay, as my account is empty. So it was only for testing right?
And if I claim and donate now, it will be also rolled back and we have to do it again after final release.
No, your claim will not be rolled back. After you claim and donate it will take long time for your transactions to show up in the history tab. You can use this tutorials -
