This has happened to me quite a few times and can be frustrating after the fact, when you are no longer able to go back and try to reselect your best answerer. It gets worse, when you actually receive a refund of the tip as well as comments from the answerers about the unfairness of the deal. I have also experienced trouble with submitting either an answer or the choice of best answer.
Sometimes the screen will freeze up and I am unable to continue. I am not sure whether this is a computer problem or a website problem. If I use the back button and try to resubmit, the site will typically tell me that my choice has already been submitted.
However, despite this confirmation, the answer still sometimes fails to submit and I will later find that my question has expired and no best answer was in fact selected.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
