I found a way to get the Normal and Dev folders to act as one folder. This makes developing and managing sins mods a lot easier.

1. Locate where the mod folders for Sins are stored. (My Games\Ironclad Games\Sins of a Solar Empire Rebellion)


2. Make sure the (Mods-Rebellion v1.86 Dev) folder is deleted. (Remember to backup your mods into the (Mods-Rebellion v1.86) folder before deleting it.)


3. Hold (Shift) and (Right Click) in a blank area and click on "Open command window here"


4. Paste this into the CMD window:
   mklink /J "Mods-Rebellion v1.86 Dev" " [INSERT THE ADDRESS FOR Mods-Rebellion v1.86 HERE] "
   
   Here's and example for how it could look:
   mklink /J "Mods-Rebellion v1.86 Dev" "D:\Documents\My Games\Ironclad Games\Sins of a Solar Empire Rebellion\Mods-Rebellion v1.86"

Hope this helps!
