Assuming the whole Mastery debacle was the result of outsourcing the DTLive website project to a budget overseas development agency (it feels a lot like when my old company did something similar, despite my protestations that it would end badly; long story short, it ended badly) and nobody within DTG has the time nor inclination to dig through the messy peasant code to find how/why it doesn't consistently do complicated sums and counting, wouldn't the best option for everyone be to just remove it? Remove it from TSW. Remove it from the Fishing Sim. Remove it from the website. You don't have to do anything as complex as stripping out all the pointless code, just hide the links, then the new generation of players coming new into the game (I'm assuming from trophy completions that the business model is built on a rapid turnover of players) will be entirely unaware it ever existed and it will increase the percentage of game features that actually work correctly. Everyone's a winner! If you choose option 3, remember that you are asking DTG to maybe take a break from releasing DLC to focus on this - prioritising this feature over the next shiny new route.
