I have a lot of saved submissions and it could be weeks to months before I submit them and before I do the characters and the lines switches for some reason. For example, in a two character scene with ten lines, Tom will say the first line then Bob will say the second, then Tom will say the third, etc. Before I submit, I check the accuracy again and for some reason the character saying each line switches orders. So now Bob will say the first line, then Tom the second, etc. When I first save them I am 100% positive I save them with the correct character saying the correct line. Can someone from imdb staff clarify why this happens and can other users tell me if this happens to them as well?
