So here it is:

I've made this month a while ago. It was working well, and I kept adding details to it.. A merchant's trade post, a bush, a plant, a dog.

Basically, I've added overall three buildings, a few NPCs (like 11) who have package and I've updated the Navmesh. That's all. Everything works, but the mod is heavy at 7 Megs, it drops the framerate at an unplayable level, and I just can't understand why. Help?

I tried the TESVEdit on it, nothing really showed up, but I'm really unsure on how to fix this...
