Resource Pack Not Showing Up On Screen While Minecraft Is In A Separate Dirrectory

Resource packs in the resource pack selection list aren't showing up when the snapshot is in a separate directory (I am running the game in a different folder, not .minecraft). I didn't know the problem at first until I switched to the default directory. That's when the resource packs showed up on my resource pack selection screen. When i switched back to my other directory, the resource packs in my resource pack folder didn't show up on my resource pack selection screen. Please fix this!
