I placed a bounty on one of my questions, expecting to select the bounty winner after the 1 week period had ended (assuming that this would allow everyone who might be interested to have a chance at providing a possibly winning answer.) This morning I went to choose the bounty winner and discovered that the bounty had disappeared and I can only select the winning answer but not assign the +100 bounty to the submitter.
What happened to that bounty? Why can't I wait the full 1 week before selecting the winner?
