Not sure where I'm going wrong. This started after I reinstalled the game after downloading RoR.

Running Windows 11. I originally downloaded the mods into my Windows download folder.

Then tried both manually installing then in the game's mod folder, as well as using the load order manager from Nexus Mods without success.

If it makes a difference, included a screenshot of my load order manager.

My question here is are you unpacking them correctly?
Like you didn't put them inside of a folder of a folder?
Mods should look like so:
