I wouldn’t necessarily call these “problems”. I just don’t like the how the underlying functionality is designed.

For some basic modding, and installing Nexus collections, it’s probably just fine, but for anything more advanced, It’s too rigid. It didn’t allow me the flexibility to do the things I wanted, and lacked plugin support for things I was already extensively using. My preference still lies with MO2, but of course, everyone is welcome to use the tools that work for them
