The only clean and safe way to repatch stuff is to uncheck the mod, reinstall it, and then repatch it. when you combine the changes, then bad stuff happens (esspecially DynDOLOD) DynDOLOD, as well as several of the other patchers at the end will actually make changes to their esp. This happens when I don't follow the instructions properly, and then I tried to run the DynDOLOD worlds gen thing a second time.
