"New Year, New You" is definitely one of the -- if not THE -- worst for tracking/timing. The first time I did it I got so frustrated that I quit it. I have gone back to it once per week and try to ignore the issues because I like the intensity.
It also doesn't display correctly on the web site, giving a "TRANSLATION MISSING" error.
I think this one was definitely rushed out the door. Until I see those things fixed, I have sworn off paying for anymore DLC.
It's sad really because this game has so much potential but is getting virtually no support from the company. I can picture all the suits at a board meeting following their next release, all puzzled as to why the new games aren't selling.
