I've included screenshots and pasted the active load order below-- I can see that it's identifying the plugins here.
Please let me know if there's anything I've missed or any additional info to include. I appreciate your help on this!
The only thing I've thought of that may have changed is having updated MO2 to the version that was released yesterday, though I, unfortunately, don't exactly recall if LOOT and SSEEdit stopped recognizing the DLC and CC plugins exactly after I'd updated or not. Otherwise, I have no idea what's changed.
