It would have made no difference which round you would have sent it.
The vote has been done.
The automated message has been updated and should have read :
"The current bidding round is full. Your bid has been submitted into the following round."

But in your special case you are the fist and only bid who filled the entire round, so the round would not have been filled without your bid.

We will calculate what size of vote you should have received with the 10% overbid protection and will refund the difference.
