I was following a tutorial with tech with time and at the end of part 4 every thing was working, part 5 just explains neat then there was implementation of neat in part 6 and by the time we tested the code again half way through part 7 (the last part) it was not working properly but no error codes.
I have tried moving the pygame.display.update() to different locations and it does not seem to help.
I have tried changing the draw order so that the birds are drawn first and then the pipes and it did not seem to help.
