When using the HCDU, it's a good idea to keep one thing in mind. It doesn't guarantee to find conflicts per se. It finds the hacks in your game modifying the same behaviours and, as such,
may conflict. When you're having a problem, the HCDU is a good starting point, but not a fail safe.

With this in mind, if you're not having any problems, then it's a judgement call you'll have to make whether to keep them both in or not. If you are having problems, then you'll need to decide which one you want to keep.
