It conflicts with the Baronness fix cause it does the same thing from scratch and fixes more. Recommended to use that one instead of the old one.
As for Silverite Mine, it's made compatible with TerraEx's Silverite Mine fix. You just have to load it after and they are compatible.
Regardless, all of the fixes that come with this new bundle of fixes are modular so you can only choose what you want in case you don't want it all.
