I recently asked a question that gave me some rep points and I want to invest all those points on this answer
I had 450+ rep, started a bounty and rewarded that answer and now that I have again 100+ I want to give it away on the same answer, but I no longer have the "Start bounty" button available on the question.
Why is that so? Is it a bug? Is there some cool-down period that I need to wait?
According to this other question I should be able to give a bounty on the same question multiple times.
