Have you ever had one of those DUH moments?

A few days ago for some odd reason, my mods just stopped working out of the blue. No matter what I did I just could not get them to work, so I took all the mods and placed them in the main folders, and they started working again. Anyways I was going through my mods folder again and discovered what the issue was. Apparently the other day, and I totally forgot about it, but I had pulled my whole mods folder, and then place it back in, but in a second Mods folder I had already set up. In short, I had a Mods folder within another Mods folder. :D The only thing I can figure out is what happened is because this all happened about the same time my grandbaby was born.

So have you ever had one of those DUH moments?
