Thanks a ton that solved my overwrite issue.
I can't seem to figure out my missing master issue. The plugin marked for error is asking for "Landscape Fixes for Grass Mods" which isn't a mod I have in my mod list, but when installing "Skyrim Landscape and Water Fixes", the installer gave me the option to select "Landscape Fixes for Grass Mods" , which I did as per the instruction of Skyrim 2021 Modding Guide. Do I need to install "Fixes for Grass Mods" as a separate mod? Or is this just a false red flag
