RQ function that saves output to file saves same output even after function is modified. #94

I have a function which I run using flask-rq which takes some input and writes to a new excel file in the server. The name of the file is result_{yyyy__mm__dd}.xlsx, hence the name of the file doesn't change for a day. This resulted in lot of trouble for me. After I noticed some error in the output I modified the function but I kept getting the same output (original output files were deleted). I finally decided to change the name of file and then I got the expected output. Is this a bug or a feature? Is redis actually storing the result, if so how can I change that?
